Financial services firms in Hong Kong hold two things criminals want most: money and data. That combination has made banks, brokers, asset managers, insurers, and wealth managers among the most heavily targeted organizations in the city, and it is also why cybersecurity sits high on the regulatory agenda.
The two main regulators, the Hong Kong Monetary Authority (HKMA) and the Securities and Futures Commission (SFC), have each built detailed expectations around how firms protect their systems, clients, and data. These are no longer broad principles. They are specific, testable requirements covering everything from how a firm authenticates a login to how it manages a third-party IT vendor.
For larger institutions with dedicated security teams, meeting these expectations is mostly a matter of resourcing and discipline. For growing firms without a large internal IT function, it is harder, since the rules do not change based on headcount, and neither do the threats.
This article covers what strong cybersecurity looks like in practice: what HKMA and SFC expect, the threats firms actually face, and the controls that make the biggest difference. It is written for CIOs, IT managers, compliance officers, and operations leaders who need both the regulatory picture and the practical steps behind it. Where outside expertise helps, we say so directly, since for many firms a managed IT and security partner is the most realistic way to close the gap.
Why Financial Services Face Unique Cybersecurity Challenges
Every business faces cyber risk, but financial firms carry a heavier burden for a few clear reasons.
The first is the value of what they hold. Client funds, trading systems, personal data, and market-moving information make a financial firm a high-value target, and attackers invest more effort accordingly, since the payoff is larger.
The second is how much of the business now runs online. As of 2023, 96.9 percent of active clients of internet brokers in Hong Kong traded online, so a security failure is not merely an inconvenience; it can halt the business and put client assets at direct risk.
The third is regulatory accountability. In most industries, a breach means cleanup costs and reputational damage. In financial services, it can also mean regulatory action, licensing consequences, and personal liability for senior managers, since both HKMA and SFC place ultimate responsibility for cybersecurity on senior management, and the SFC specifically names the Manager-in-Charge of Information Technology (MIC-IT).
Finally, there is dependence on outside providers. The SFC found that 92 percent of internet brokers use systems from third-party providers, and 70 percent rely on just five vendors, a concentration that means a weakness at one supplier can ripple across a large part of the market at once.
What HKMA and SFC Actually Expect
Hong Kong does not have one cybersecurity rulebook for the whole financial sector. Banks and deposit-taking institutions answer to the HKMA. Licensed corporations, including brokers, asset managers, and fund managers, answer to the SFC. The two frameworks differ in detail, but they are converging, and understanding both helps any firm benchmark its own position.
HKMA: The Cybersecurity Fortification Initiative
The HKMA's approach centers on the Cybersecurity Fortification Initiative (CFI), first rolled out in 2016 and updated repeatedly since. It applies to Authorized Institutions (AIs), and its most important component is the Cyber Resilience Assessment Framework (C-RAF), which asks each institution to assess its own inherent risk and then demonstrate that its resilience matches that risk, rather than applying one fixed standard to everyone.
The HKMA has continued to expand its focus on cyber resilience. A June 2026 circular urged vigilance against AI-powered threats and required AIs to confirm whether current controls still hold up, flagging layered defenses against zero-day vulnerabilities, prompt patching, scrutiny of third-party and cloud provider resilience, and tested incident response playbooks. It also revisited Secure Tertiary Data Backup, suggesting that any AI without it should reconsider that decision. A new testing framework and critical-infrastructure obligations for designated banks are also on the way.
SFC: From Baseline Guidelines to Active Enforcement
The SFC set its baseline in 2017 with the Guidelines for Reducing and Mitigating Hacking Risks Associated with Internet Trading, setting out 20 baseline requirements for licensed corporations offering internet trading.
What makes the SFC's position particularly useful is its 2023/24 Thematic Cybersecurity Review, published in February 2025, which covered 50 licensed corporations and is unusually specific about where firms fell short. It is one of the more practical documents any Hong Kong licensed corporation can read to understand what the SFC actually expects, and much of the detail below draws from it.
More recently, a June 2026 circular required licensed corporations and virtual asset service providers to review and strengthen their cybersecurity against AI-enabled attacks, again naming senior management, including the MIC-IT, as ultimately accountable. The SFC has also signaled plans for an industry-wide framework covering all licensed corporations, not just those offering internet trading.
Where the Two Converge
Despite covering different types of firms, HKMA and SFC increasingly ask for the same things: a risk-based approach rather than a checklist, personal accountability for senior management, and sharper focus on third-party risk, patching, access controls, and readiness for AI-enabled attacks.
That convergence is useful in practice. A firm that builds a solid, well-documented security program will find it is already meeting most of what either regulator asks, and the controls covered later in this article map to both frameworks.
The Threat Landscape Facing Hong Kong Financial Firms
Regulatory pressure exists because the threats are real and growing. Cyber incidents in Hong Kong rose 27 percent in 2025 to 15,877, up from 12,536 the year before, and financial firms sit close to the center of that trend, according to HKCERT data.
Phishing is the dominant problem. In 2024, phishing accounted for 62 percent of all security incidents handled by HKCERT, the most severe phishing situation in five years and a 108 percent jump from 2023, with over 48,000 phishing links recorded, a 150 percent increase. The banking, finance, and e-payment sectors took the brunt of it.
Malware is rising alongside it, growing nearly five-fold year on year in 2024, mostly trojans disguised as legitimate applications. The two threats often work together: a phishing email delivers the malware, which then opens the door to theft or ransomware.
Ransomware remains one of the most damaging outcomes. In one case the SFC cited, a licensed corporation had to rebuild its entire IT system after ransomware encrypted all of its data, and several reported incidents traced back to end-of-life operating systems and unpatched VPNs. This illustrates how often attacks succeed through basic, preventable weaknesses rather than sophisticated techniques.
Two newer trends are worth watching. The first is supply chain attacks: rather than targeting a well-defended firm directly, criminals breach a smaller, weaker third party with access to the target and move through that connection, a real structural risk given how heavily Hong Kong firms rely on the same handful of vendors. The second is AI-enabled attacks, flagged by both regulators in their 2026 circulars. Frontier AI can plan multi-step attacks, hunt for zero-day vulnerabilities, and run convincing phishing and deepfake impersonation campaigns, which lowers the skill required to carry out a sophisticated attack. Defenses considered adequate a year ago may no longer be sufficient.
Essential Security Controls Every Financial Firm Should Have
Most successful attacks exploit a familiar set of weaknesses, and the controls that stop them are well understood. The SFC's thematic review essentially reads as a list of the gaps that let attackers in, making it a practical checklist for anyone building or auditing a program.
Identity and Access Management
Controlling who can access what is the foundation of security. The SFC's review found firms handing out admin access far too widely, and others with no audit trail to show who did what on critical systems, both of which make it easy for an attacker, or a careless insider, to cause real damage unnoticed.
The standard to aim for is least-privilege access across the board: every user and service account gets only the access their role needs, administrative rights are tightly controlled and reviewed regularly, and senior management reviews the remote access user list at least once a year. Reliable logging matters just as much; a firm that cannot reconstruct who accessed a system cannot investigate an incident or demonstrate compliance. This is detailed, unglamorous work, and it is an area where an IT security audit often turns up stale permissions that have quietly built up over years.
Multi-Factor Authentication
Passwords alone are no longer sufficient, and both regulators expect multi-factor authentication (MFA) on sensitive access. The SFC specifically flagged weak two-factor setups as a deficiency, calling out SMS one-time passwords in particular, since they can be intercepted or hijacked through SIM-swap fraud. Authenticator apps, hardware security keys, and push-based approvals tied to a registered device are stronger alternatives, and the SFC expects at least two factors on every remote access connection.
MFA is one of the highest-value controls any firm can deploy, since it blocks the large share of attacks that start with a stolen or guessed password. If a firm still relies on SMS codes, or has any sensitive system protected by a password alone, that is worth addressing first.
Email Security and Anti-Phishing
Since phishing drives the majority of incidents in Hong Kong, email deserves particular attention. The SFC set a clear behavioral rule here: firms should not send emails or texts with links asking clients to log in or transact. Training clients to click links from a firm makes it easier for an attacker impersonating that firm to succeed.
On the technical side, firms need solid email filtering to catch malicious messages before they reach an inbox, along with authentication standards that make it harder to spoof the firm's domain. Technology alone does not stop phishing, however, since the attack targets people rather than systems, which is why training and phishing simulations, covered later, count as core controls rather than optional extras. This is a common focus area for Microsoft 365 management, where filtering, authentication, and anti-phishing policies are tuned to the firm.
Endpoint Protection and Patch Management
Endpoints, meaning the servers and workstations staff use every day, are where many attacks land. The SFC found firms that had not installed anti-malware on every machine, and others running outdated signatures; the baseline expectation is anti-malware everywhere, kept current.
Patching was one of the most common failures in the review, with firms delaying security patches and leaving known vulnerabilities open. Both regulators now stress prompt patching, including a fast-track process for urgent fixes outside the normal cycle.
End-of-life software makes patching impossible, since vendors stop issuing fixes. Notably, half the firms surveyed were still running end-of-life systems, including Windows Server 2008 and Windows 7, with no real plan for retiring them. The remedy is a clear IT asset management policy that tracks what is nearing end of life and reviews the full inventory annually. Keeping every endpoint patched and current is exactly the kind of ongoing discipline that managed IT support is built to maintain.
Vulnerability Management and Penetration Testing
Firms cannot fix weaknesses they do not know about. Vulnerability management is the ongoing work of scanning systems, identifying gaps, and closing them before an attacker does, and it depends on an accurate, current inventory of every technology asset, from hardware and software to network equipment and cloud services.
Penetration testing goes further by simulating a real attack to determine what is actually exploitable. The SFC expects firms to request penetration test reports as part of vendor due diligence, and regular testing of a firm's own environment turns assumptions into evidence. Configuration weaknesses belong in this category as well: the review found weak firewall and server configurations, outdated encryption, and insufficient encryption of data in transit and at rest. Strong, current encryption and hardened configurations are a baseline expectation, and a structured IT security audit tends to surface these issues faster than day-to-day operations typically will.
Security Monitoring and Managed Detection and Response
Prevention is never perfect, so detection matters just as much. The faster a firm spots an intrusion, the smaller the damage, and both regulators expect stronger threat detection, better threat intelligence, and the ability to act quickly once something surfaces.
Effective monitoring means watching systems around the clock and having someone able to respond at 3 a.m. as readily as 3 p.m., which is difficult to sustain for a firm without a dedicated security team. That is why many turn to managed detection and response, where a specialist provider monitors the environment and escalates genuine threats. The SFC's 2026 circular also calls for pre-planned containment: the ability to block malicious activity, isolate affected systems, and restrict access quickly. For most growing firms, security monitoring delivered as a managed service is the realistic way to achieve continuous coverage without building an in-house team from scratch.
Managing Third-Party and Vendor Risk
Given how heavily Hong Kong financial firms rely on outside providers, this is one of the most important areas to address, and one where the SFC found the widest gaps: no real third-party risk policy, weak SLAs, thin due diligence, and business continuity plans that never accounted for a vendor's own cybersecurity failure.
Due diligence needs to happen before a provider is appointed, not after. That means checking a provider's security controls, reviewing independent assurance such as SOC 2 or ISO 27001, and requesting penetration test reports; a provider that cannot produce any of this is a warning sign in itself. Contracts should carry real weight too, with SLAs specifying cybersecurity requirements and incident reporting timelines so that a breach at the provider reaches the firm quickly enough to protect its own clients.
Remote access by third parties needs particularly tight control. The SFC's standard is straightforward: no permanent remote access rights for outside providers, with all activity logged and monitored, and its 2026 circular calls on firms to strengthen supply chain governance further. Because so many firms depend on the same small pool of vendors, taking supplier risk seriously is not simply good hygiene; it is a defense against a genuinely systemic weakness in the market.
Securing Cloud and Microsoft 365 Environments
Most financial firms now run key workloads in the cloud, from email and document management to trading and back-office systems. Cloud brings real benefits, but it also introduces configuration risks the SFC found firms mishandling repeatedly: no network segmentation, weak backup practices, no immutable or air-gapped backups, and daily backup requirements simply not being met.
Network segmentation is a core expectation. Rather than leaving everything on one flat network where a single breach can reach anything, segmentation divides the environment so an intrusion stays contained, and both regulators stress firewalls and segmentation as part of a defensible architecture. Access to cloud infrastructure needs equally tight control: two-factor authentication combined with IP whitelisting for root accounts, least-privilege access for cloud credentials, and API keys that are rotated rather than left as permanent, standing keys, since over-privileged credentials are one of the most common ways attackers get into cloud environments.
Backup deserves particular emphasis. The SFC expects daily, offline, immutable backups that are air-gapped and write-once, read-many, so ransomware cannot alter them, which echoes the HKMA's own attention to Secure Tertiary Data Backup for banks. For the many firms running on Microsoft 365, much of this comes down to configuration: identity protection, conditional access, MFA policies, and secure sharing settings, set up correctly and revisited as the environment changes. Getting Microsoft 365 management right closes a large share of the gaps the SFC identified, simply because so much day-to-day risk lives inside that platform.
Preparing for the Worst: Incident Response and Business Continuity
No set of controls is perfect, so firms must plan to be breached. Both regulators treat incident response and recovery readiness as central: the HKMA expects AIs to keep their playbooks current and run scenario testing, while the SFC expects plans that cover phishing scenarios, including a full system shutdown if needed, along with pre-planned containment strategies.
A useful incident response plan is specific. It names who does what, how decisions get made under pressure, how systems are isolated, and how clients and regulators are informed. A plan that exists only as a document, and has never been tested, is unlikely to hold up well during a real incident.
Testing therefore matters as much as the plan itself. Both regulators call for regular tabletop exercises and simulated attacks to confirm that people actually know their roles. These exercises routinely reveal gaps, an outdated contact list, an unclear decision path, that are far cheaper to fix in a drill than in a live incident.
Backups underpin the whole recovery process, and the SFC's emphasis on immutable, air-gapped backups exists precisely so recovery is possible even after ransomware. Firms should also apply maker-checker controls on high-impact actions, so that a single compromised account cannot cause catastrophic damage alone. Reporting is mandatory too: the SFC requires prompt notification of material incidents, so knowing what counts as material, and who needs to be told within what window, belongs in the plan rather than being worked out mid-crisis. Building and rehearsing a response plan is an area where outside IT consultancy genuinely adds value, since an experienced partner has seen how incidents actually unfold, not only on paper.
Securing Hybrid and Remote Work
Hybrid and remote work are now standard in financial services, and they expand the ways an attacker can gain entry. The SFC's review found real weaknesses here: no two-factor authentication or VPN on RDP and SSH connections, and unpatched VPN software, in some cases left unpatched for over a year, a gap that showed up repeatedly in real reported incidents.
The standard is straightforward. Remote access should only be possible through a VPN or equivalent, such as Virtual Desktop Infrastructure, protected by MFA, with session timeouts so idle connections do not remain open indefinitely. Direct, unprotected remote access into internal systems should not exist at all.
Third-party remote access needs the tightest handling of all: no permanent access rights, full logging, and an annual review of who is on the list. Because remote access is such a common entry point, keeping VPNs patched, enforcing MFA, and controlling who is allowed to connect are among the highest-priority tasks for any firm supporting flexible work. It is also a natural fit for ongoing managed IT support, which keeps remote access infrastructure patched and correctly configured on an ongoing basis rather than as a periodic exercise.
Building a Security-Aware Culture
Technology stops many attacks, but people remain both the biggest target and the strongest line of defense. Given that phishing drives most incidents in Hong Kong, staff awareness is not a soft extra; it is a core control regulators expect firms to have.
The SFC expects regular cybersecurity awareness training for all staff, with phishing specifically covered. Training should be ongoing rather than a one-time induction, since threats change and lessons fade, and it should be practical, showing staff what today's phishing and social engineering actually look like, including the more convincing attacks AI now makes possible.
Phishing simulations turn training into practice, and many firms run them quarterly. Sending controlled fake phishing emails lets a firm see who clicks, follow up with targeted coaching, and track improvement over time, building genuine instinct rather than resentment.
Culture goes beyond training as well. Staff need to feel safe reporting a mistake, such as clicking a bad link, without fear of blame, since early reporting is often the difference between a contained incident and a major breach. Senior management sets that tone, and its visible commitment matters given that it carries ultimate responsibility for cybersecurity governance. Structured cybersecurity training gives firms a repeatable way to build and measure this awareness across the organization.
How Managed IT Services Can Strengthen Your Security Posture
Reading through all of this, the challenge for smaller and growing firms is clear. The regulatory bar does not move based on firm size, but the resources to meet it do, and doing this well takes specialist skills across identity, endpoint security, cloud, monitoring, incident response, and vendor management, plus the ongoing time to keep it current.
Many financial firms in Hong Kong do not have a large internal IT team and already rely on third-party providers. Used well, that dependence is an advantage rather than a weakness: a capable managed IT and cybersecurity partner brings depth and continuous coverage that would be costly to build in-house. The value shows up across several areas: managed IT support keeps systems patched day to day, security monitoring provides the continuous watch regulators now expect, an IT security audit benchmarks the firm against HKMA and SFC expectations with a prioritized plan to close gaps, and training and phishing simulations build the staff awareness that stops most attacks at the front door.
One important caveat: using a managed provider does not transfer regulatory responsibility. That remains with the firm's senior management, including the MIC-IT. What a good partner provides is the tools and confidence for senior management to meet a responsibility that is already theirs, and to demonstrate to regulators that cybersecurity is being taken seriously.
Choosing the Right IT Partner in Hong Kong
If outside support makes sense for a firm, the same due diligence standards the SFC expects of any third-party provider should apply to whoever is trusted with its security.
Start with genuine familiarity with the financial services regulatory environment. A partner who understands the HKMA and SFC frameworks, and has actually helped firms meet them, saves considerable back-and-forth translating technical work into compliance language.
Second, examine the partner's own security credentials, the same way the SFC expects firms to vet any vendor: ask about independent assurance such as SOC 2 or ISO 27001, and how they handle their own penetration testing and incident reporting.
Third, weigh breadth and continuity. The controls in this article span identity, endpoints, cloud, monitoring, training, vendor management, and incident response, and they need to be maintained over time rather than delivered once, so a partner covering all of it under one roof is more practical to manage.
Finally, consider local presence and responsiveness. When an incident happens, response time matters, and a partner with people on the ground in Hong Kong can respond faster. FunctionEight provides managed IT and cybersecurity services from Hong Kong and Singapore, supporting businesses that need dependable IT operations, stronger security controls, and responsive regional support.
Conclusion
Cybersecurity for Hong Kong financial services has moved from a technical concern to a central business and regulatory obligation. HKMA and SFC have set out detailed, testable expectations, and they are raising the bar further as AI-enabled and supply chain attacks reshape the threat landscape. The rising incident count in the city, driven heavily by phishing and increasingly by ransomware, illustrates why this attention is warranted.
The encouraging part is that the controls satisfying regulators are the same ones genuinely protecting a firm and its clients. Strong identity and access management, phishing-resistant MFA, disciplined patching, careful vendor management, well-configured cloud environments, tested incident response, and a security-aware culture together address the great majority of real-world attacks. None of this is exotic; it is a matter of doing the fundamentals well and keeping them current.
For firms without a large internal IT team, the realistic path is building the right controls with the right help. A capable managed IT and cybersecurity partner can turn a demanding list of requirements into a manageable, ongoing program, while senior management retains the accountability regulators rightly place on it. FunctionEight provides managed IT support, security monitoring, audits, and staff training to help businesses across Hong Kong and Singapore build exactly this kind of program.
