Malaysia's cybersecurity market has grown rapidly, and so has the number of companies calling themselves penetration testers. Some run automated scanners and dress up the output as a manual pentest. Others lack the certifications required by Bank Negara Malaysia's RMiT framework or the new Cybersecurity Act 2024. Getting this vendor selection wrong can mean a failed regulatory audit, a missed critical vulnerability, or a data breach that could have been prevented.
This guide walks you through the 10 factors that actually differentiate a serious penetration testing company from one that will waste your budget and leave your systems exposed.
1. CREST and OSCP Certifications
Certifications are the single fastest filter you can apply. At the organisational level, look for CREST accreditation — the Council of Registered Ethical Security Testers is the body recognised by Bank Negara Malaysia under the RMiT framework and by the Monetary Authority of Singapore. At the individual tester level, look for OSCP (Offensive Security Certified Professional), CREST CRT/CCT, or equivalent credentials.
CREST company accreditation requires evidence of quality management processes, staff training programmes, and insurance — not just technical skill. OSCP proves a tester can compromise real systems under exam conditions without guidance. Together, these credentials confirm both organisational rigour and individual hands-on competence.
What to ask the vendor
“Can you share your CREST accreditation certificate and the certifications held by the testers assigned to our engagement?”
2. NACSA Service Provider License
Malaysia's Cybersecurity Act 2024 mandates that cybersecurity service providers serving Critical National Information Infrastructure (CNII) sectors — banking, energy, water, telecommunications, and government — hold a valid NACSA (National Cyber Security Agency) licence.
Even if your organisation does not fall under CNII, selecting a NACSA-licensed provider is a strong signal of regulatory seriousness. It means the company has been vetted by the national cybersecurity authority, carries appropriate professional indemnity insurance, and operates within Malaysia's legal framework for handling sensitive data. Ask to see a copy of the licence and verify it against the NACSA registry.
3. Recognised Methodology: OWASP, PTES, and OSSTMM
A credible penetration testing company follows a documented, reproducible methodology. The three most widely accepted frameworks are:
- OWASPThe Open Web Application Security Project provides the testing guide and Top 10 that define baseline web application testing coverage.
- PTESThe Penetration Testing Execution Standard covers the full engagement lifecycle — from pre-engagement and intelligence gathering through exploitation to post-exploitation and reporting.
- OSSTMMThe Open Source Security Testing Methodology Manual is preferred for infrastructure and network assessments, providing metrics-driven, auditable test coverage.
Ask the vendor which methodology they follow for your specific engagement type and request a copy of their methodology documentation. If they cannot produce one, that is a red flag.
4. Scope Definition and Rules of Engagement
Vague scope leads to missed vulnerabilities and accidental disruption of production systems. A professional penetration testing company will spend time before the engagement defining:
- Exact IP ranges, domains, and applications in scope
- Out-of-scope assets and explicit exclusions (e.g. third-party SaaS, shared hosting)
- Permitted testing techniques (e.g. social engineering, physical access)
- Testing windows to minimise production impact
- Emergency contact procedures if a critical finding requires immediate notification
Scope clarity protects both parties legally and ensures the report reflects your actual attack surface rather than whatever the tester happened to discover.
5. Report Quality and Actionability
The deliverable of a penetration test is the report. A vulnerability scanner can produce a list of CVEs — a skilled human tester produces a narrative that explains how weaknesses chain together into a realistic attack scenario. Before engaging any vendor, request a redacted sample report.
A high-quality pentest report contains:
Executive Summary
Risk posture in plain English for board and senior management, without technical jargon.
CVSS-Scored Findings
Each vulnerability rated by severity with a Common Vulnerability Scoring System score and business impact statement.
Evidence and PoC
Screenshots, payloads, and proof-of-concept steps showing the vulnerability is real and exploitable, not theoretical.
Prioritised Remediation
Concrete fix steps ordered by risk — not just 'upgrade the library' but exact configuration changes or code fixes.
Attack Narrative
A walkthrough of how an attacker could chain findings to achieve a meaningful impact like data exfiltration or full domain compromise.
Compliance Mapping
Mapping of findings to relevant standards (RMiT, PDPA, PCI-DSS) where applicable.
6. Remediation Retesting Policy
Finding vulnerabilities is half the job. Confirming they are fixed is the other half. Ask every prospective vendor: “Does your engagement include a remediation retest?”
A retest — conducted 30 to 90 days after the initial report — verifies that each critical and high-severity finding has been correctly remediated and has not introduced new issues. Without a retest, you have no assurance that your remediation efforts actually closed the gaps. Some vendors charge separately for retests; the best providers include at least one full remediation retest cycle in the base engagement cost. Confirm this in writing before you sign the statement of work.
7. NDA and Data Confidentiality Procedures
A penetration test gives a third party deep access to your systems, source code, and potentially customer data. The confidentiality agreement must be robust and specific. Look for:
- A bilateral NDA signed before any scoping discussions begin
- Explicit data handling clauses covering where testing data is stored and for how long
- Data destruction or return procedures at engagement close
- Staff vetting disclosures — background checks on personnel who will access your environment
- Incident notification obligations if data is inadvertently accessed or exfiltrated during testing
Under Malaysia's PDPA, you are responsible for the personal data your processor (the pentest vendor) handles. Ensure the NDA and data processing agreement are reviewed by your legal team before signing.
8. Pricing Transparency
Opaque pricing is a warning sign. A trustworthy penetration testing company provides a detailed proposal that breaks down:
- The number of tester-days allocated to the engagement
- What is included versus what attracts additional charges (e.g., retests, extra applications added mid-engagement)
- Travel or on-site expenses for internal network assessments
- Report writing time as a separate line item
Beware of suspiciously low quotes. A realistic web application penetration test requires a minimum of 3–5 tester-days of manual effort. If the price implies one or two days of work, you are likely paying for an automated scan with a branded cover page. At the other extreme, inflated day rates from large consulting firms do not automatically translate to better findings — evaluate on credentials and sample work.
Red Flag: The Automated Scan Dressed as a Pentest
If a vendor delivers a report within 24–48 hours of receiving your scope, it is almost certainly automated tool output. Tools like Nessus and Burp Suite are useful starting points, but they cannot chain vulnerabilities, test business logic flaws, or assess authentication bypass scenarios. A genuine manual pentest takes days, not hours.
9. Local Malaysian Presence and Regulatory Knowledge
International penetration testing firms may be technically competent but lack working knowledge of Malaysia's specific regulatory landscape. A local provider with in-country expertise understands:
- Bank Negara RMiT: The Risk Management in Technology framework's specific requirements for penetration testing frequency, scope, and remediation timelines for financial institutions.
- PDPA 2010: How findings intersect with Malaysia's Personal Data Protection Act and your obligations as a data controller.
- Cybersecurity Act 2024: Incident reporting obligations and CNII designation criteria that affect how you classify and respond to critical findings.
- SC (Securities Commission) guidelines: Relevant for capital market operators, fund managers, and licensed digital asset exchanges.
A Kuala Lumpur-based team can also respond rapidly to emerging findings during a test without the latency of offshore coordination, and can attend regulator meetings or audit sessions alongside your internal team.
10. Client References and Verifiable Case Studies
Past work is the strongest predictor of future performance. Any credible penetration testing company should be able to provide:
- Two or three client references in your industry vertical willing to speak on the record or take a call
- Redacted case studies showing engagement type, findings, and remediation outcomes
- Evidence of work with regulated sectors (banking, insurance, healthcare, government) if that is your context
Do not accept logo walls as a substitute for references. A company can display a bank logo if it sold that bank a software licence — it does not mean they conducted a penetration test. Speak directly with a security or IT manager at the reference organisation and ask specifically about report quality, tester professionalism, and whether they identified findings that automated tools missed.

Frequently Asked Questions
Does a penetration testing company in Malaysia need to be NACSA licensed?
Under the Cybersecurity Act 2024, entities providing cybersecurity services — including penetration testing — to Critical National Information Infrastructure (CNII) owners must hold a valid NACSA service provider license. For non-CNII engagements the license is not legally mandated, but choosing a licensed provider signals regulatory compliance and professional accountability.
What is the difference between CREST and OSCP for penetration testers?
CREST is an organisational and individual accreditation body recognised by Bank Negara Malaysia's RMiT framework. OSCP (Offensive Security Certified Professional) is an individual hands-on certification from Offensive Security that proves practical exploitation skills. Both are respected; for Malaysian financial institutions, CREST accreditation at the company level is often a regulatory requirement, while OSCP signals deep individual technical skill.
How much does a penetration test cost in Malaysia?
Pricing varies by scope, methodology, and provider credentials. A focused web application pentest for a small business can start around RM 5,000–RM 10,000, while a comprehensive network and application assessment for an enterprise or financial institution can range from RM 30,000 to RM 150,000+. Beware of unusually low quotes — they often reflect a vulnerability scan rather than genuine manual testing.
What should a good penetration test report include?
A professional pentest report should contain an executive summary for leadership, a technical findings section with each vulnerability's CVSS score and evidence (screenshots, payloads, proof-of-concept), clear remediation steps prioritised by risk, and an attack narrative explaining how findings chain together. Reputable firms also include a remediation retest at no extra charge within 30–90 days.
How long does a penetration test take in Malaysia?
Timeline depends on scope. A single web application typically takes 5–10 business days. A full internal network assessment for a mid-size organisation may take 2–4 weeks. Rushed timelines are a red flag — thorough manual testing cannot be compressed without sacrificing quality.
