01
Every engagement is led by certified white-hat testers
Every test is delivered by UD's in-house team and never outsourced to a third party. We use the same techniques as real attackers, finding your flaws one step ahead of them.
What is penetration testing?
An annual health check for your business, not first aid after a breach.
Penetration testing commissions white-hat (ethical) hackers to simulate real attacks on your systems, surfacing and ranking flaws before attackers do.
Run remotely or on-site, covering websites, networks, mobile apps, internal networks and operating systems, with compliance-ready report formats.
Why Hong Kong businesses choose UD penetration testing
02
Reports map straight to regulators and audits
Run to OWASP Top 10, PTES and NIST SP 800-115, mapping to ISO 27001 Annex A, PCI-DSS 11.3, PDPO Principle 4 and HKMA TM-G-1 / TM-E-1, ready to hand to auditors and the board.
03
Retest included, we close only when fixes hold
We retest every identified flaw and issue a Clearance Letter, giving quantified proof of reduced risk; reports include CVSS, business impact and fix priority.
04
AI intelligence for both speed and depth
AI accelerates asset discovery, vulnerability correlation, false-positive filtering and attack-path simulation, freeing experts for the highest-risk business logic and complex attack chains. Every critical flaw is still verified by hand by OSCP-level engineers, AI handles volume, experts handle quality.
05
Local delivery, sensitive data never leaves Hong Kong
Serving over 4,000 Hong Kong and multinational firms since 1998, bank site-launch audits, NGO donation-platform access flaws, large festival back-ends and annual school audits are all in our case files. A 100% local, directly hired team.
Our team holds 17 cybersecurity certifications
What we can test for you
We cover the six attack surfaces most businesses share, following OWASP, PTES and NIST methodologies, with report formats tuned to your compliance target. Need several layers tested? We'll combine them into a single engagement.

A standardised testing process
About 4–5 weeks end to end01
Kickoff & scoping
Confirm targets, assets and authorised scope; sign the Rules of Engagement (RoE).
02
Recon & scanning
Commercial scanners set a baseline; the AI engine correlates flaws and filters false positives.
03
Manual testing & exploitation
White-hats verify OWASP issues, privilege escalation and lateral movement.
04
Reporting & debrief
Deliver a report with CVSS, PoC and fix advice, then walk you through it.
05
Retest
Retest fixed flaws and issue the Clearance Letter.
Which businesses need it
Any organisation holding large volumes of personal data, processing payments, or heavily reliant on system uptime should budget for an annual pen test, especially those under PDPO, PCI-DSS, HKMA, SFC or ISO 27001.

Best practice · Scan quarterly, pen test annually; DPO-scope bodies add SRAA. The three aren't mutually exclusive, they work together.
Penetration testing vs vulnerability scanning
They complement rather than compete: best practice is a quarterly scan cadence plus an annual pen test.

Frequently asked questions
How is penetration testing different from vulnerability scanning?
Vulnerability scanning is automated, continuous and broad but shallow, mainly identifying known CVEs; penetration testing is hands-on, with white-hats simulating attacks in depth, chaining several low-risk flaws into a full attack path and verifying business-logic flaws. Best practice is quarterly scans plus an annual pen test; DPO org-level audits should separately consider SRAA.
How do we get a quote, and what do you need from us?
Submit the form at the foot of the page noting your target type (website, mobile app, network, intranet, etc.), rough scale (number of pages, user roles, API endpoints), compliance needs and timing. A UD security expert will reply shortly to arrange a scoping meeting, after which we provide a formal quote.
Will the test disrupt our live business?
Timing and testing methods are agreed during scoping. High-risk actions (such as DoS simulation or brute-forcing) are run outside peak hours or in a staging environment; routine OWASP testing keeps any impact on production extremely low. We sign Rules of Engagement before every test, clearly defining what is off-limits.
How often should we test, and when is it most effective?
At least once a year. Add a test in these moments: before a new system or site goes live, after major architecture changes (cloud migration, core system upgrades), before compliance audits (ISO 27001, PCI-DSS, HKMA), as due diligence ahead of a merger or acquisition, and as a post-mortem after a suspected incident.
Can the report go straight to external auditors or regulators?
Yes. Our reports follow OWASP, PTES and NIST standards and can map to ISO 27001 Annex A, PCI-DSS Requirement 11.3, HKMA TM-G-1 and HKPDPO Principle 4 as needed, and they have been cited by multinational banks, listed-company audits and the Privacy Commissioner.
Can a pen test guarantee we won't be hacked?
No, and that's the honest industry answer. A penetration test is a point-in-time, scoped snapshot. For continuous security, pair it with MSSP 24/7 managed monitoring, regular vulnerability scans and staff phishing tests.
We have in-house IT, do we still need to outsource the pen test?
Yes. First, independence: a team testing its own systems has a conflict of interest, while an external tester carries audit weight. Second, attacker expertise: white-hats handle hundreds of engagements a year and stay on top of the latest techniques. Third, compliance: PCI-DSS, ISO 27001 and others explicitly require an independent third party.
Does AI intelligence cost you testing depth or reliability?
No. In the UD process, AI only speeds up the repetitive work, asset discovery, vulnerability correlation, false-positive filtering and attack-path simulation, leaving human time for the parts that need judgement. Every medium- and high-risk flaw is ultimately verified by hand by an OSCP-level white-hat, with proof of concept, reproduction steps and fix advice. Put simply: AI handles volume, experts handle quality.
