Top 7 Cyber Security Audit Agencies in Malaysia 2026

All seven audit providers operate inside the Klang Valley corridor (Kuala Lumpur, Petaling Jaya, Cyberjaya) and can issue audit reports in either Bahasa Malaysia or English as required by MAMPU and Bank Negara inspection teams. They are ordered by how much of the 2026 audit workload each one can realistically absorb: testing depth, regulatory acceptance, and available certification slots.

1. CyberSecurity Malaysia

CyberSecurity Malaysia is the designated national authority and the de facto baseline for any government-linked audit chain. Its Security Assurance division performs vulnerability assessments and penetration tests on federal systems, and national critical information infrastructure (NCIIP) operators in banking, energy, transport, and healthcare treat their gap analysis reports as a mandatory first pass before bringing in a private firm.

Under the Cybersecurity Act 2024 (in force since 26 August 2024), CyberSecurity Malaysia coordinates respect of audit schedules and security incident reporting for NCIIP sectors. In 2026, the practical consequence is that most GLCs and statutory bodies will run CyberSecurity Malaysia’s own assessment first, then layer a private pen test on top for their annual risk committee meeting. Their costing is significantly lower than Big 4 rates, and audit teams are familiar with MAMPU’s MyGovSec requirements, which private-sector auditors rarely read.

Best for: Federal agencies, GLCs, and NCIIP operators that need a regulator-facing baseline before any commercial audit.

2. LGMS Berhad

LGMS Berhad is the only pure-play cybersecurity audit firm listed on Bursa Malaysia’s ACE Market, headquartered in Petaling Jaya. Their core business is the exact technical audit work that Bank Negara’s RMiT policy document (BNM/RH/STD 31-2018) demands: Technical Risk & Threat Assessments on internet-facing banking services, mobile apps, payment gateways, and ATM switching infrastructure. Their auditors work hands-on with Burp Suite, Nessus, Metasploit, and custom exploit chains rather than pasting scan output into a PDF.

For 2026, LGMS is the default pick for licensed financial institutions, digital banks, and remittance providers because their reports are structured to answer specific RMiT sections (e.g., TIA gap analysis, system resilience testing). They also run PCI DSS Level 1 gap assessments for card-processing merchants, which keeps them inside the same audit cycle as the annual bank review. Expect 60–120 page reports with retest procedures and signed risk acceptance forms.

Best for: Licensed banks, e-wallet operators, and remittance firms that need RMiT-compliant audit output the examiner will not re-question.

3. Securemetric Berhad

Securemetric Berhad is an ACE Market-listed identity and cybersecurity firm that specialises in the layer most KL auditors cannot test: the identity stack. Their audit division concentrates on IAM entitlement reviews, privileged access management (PAM) configuration checks, PKI key ceremonies, and hardware security module (HSM) compliance. Because Securemetric also manufactures the SecureOTP hardware tokens and runs managed PKI for banks and government agencies, their testers know exactly where Malaysian implementations typically drift from ISO 27001 Annex A controls.

In 2026, expect Securemetric to handle fintech and e-wallet audits where the regulator asks for evidence that eKYC data flows are encrypted at rest and in transit across both web and mobile channels. Their audit output is narrower than LGMS but pre-validated for the local financial sector.

Best for: Fintech companies and digital banks using PKI, token-based 2FA, or eKYC pipelines that need one layer audited deeply before the main RMiT review.

4. BDAS

BDAS is the offensive-security shop in the Klang Valley that product teams call right before a listing, an institutional funding round, or a Bursa board-level attestation that requires a genuine penetration test report. Their methodology is manual: OWASP Top 10-based testing of live production endpoints, business logic flaws, session management, and authorisation bypasses — the kind of findings automated scanners miss. The responsible disclosure output is written for engineers, not just governance committees, and includes exploit reproduction steps.

BDAS also runs one of Malaysia’s most accessible offensive-security training pipelines; their keying certification courses are attended by SOC analysts from local banks and insurers, meaning their auditor pool is fed from people who actually work inside Malaysian enterprise networks. They are not the cheapest option, but their reports survive scrutiny from overseas investors who ask hard questions about dependency-chain and API-layer exposures.

Best for: SaaS vendors in Bangsar South and Petaling Jaya, plus late-stage startups preparing for institutional due diligence.

5. PwC Malaysia

PwC Malaysia’s cybersecurity practice, based at 1 Sentral in Kuala Lumpur, is the audit agency of record for the SOC 1 / SOC 2 attestations and ISO 27001 certification audits that Malaysian subsidiaries of global banks and engineering firms must produce for overseas parent reporting. They also run the management-consultant layer of cyber audits: defining risk appetite, running board-level tabletop incident simulations, and converting a penetration test report into a prioritised budget request that a CFO will approve.

For 2026, PwC remains the strongest route for cross-border subsidiaries that need a single audit language that Singapore, Hong Kong, and London compliance teams will accept without re-formatting.

Best for: Malaysian subsidiaries of MNCs and larger GLCs that need global-recognised attestation reports with a governance wrapper.

6. Deloitte Malaysia

Deloitte Malaysia’s cyber risk practice, part of Risk Advisory, is the common pick for mid-cap main-board listed companies that lack a dedicated CISO. Starting with the Bursa Malaysia Cybersecurity Framework effective 1 June 2025, listed issuers are required to establish board-level cyber governance; Deloitte answers that with a maturity assessment scored against the NIST CSF and the Bursa framework’s pillar structure (governance, identification, protection, detection, response and recovery).

Deloitte’s deliverable for 2026 is deliberately director-friendly: a gap score, a 90-day remediation roadmap, and a set of key risk indicators that the audit committee can track each quarter. They layer on penetration tests through their regional delivery centre, but the unique value is the board semantics, not exploit depth.

Best for: Mid-cap companies on the Main Market that need to show the board a measurable cyber maturity baseline before the next annual report.

7. KPMG Malaysia

KPMG Malaysia’s Cyber Security Services team holds a niche that is severely under-supplied in Malaysia: audit of operational technology (OT/SCADA) environments. While most Klang Valley agencies can only test TLS/IT networks, KPMG’s OT auditors assess energy, water treatment, and port authority systems against ISA/IEC 62443, in addition to handling ISO 27001 certification and recertification audits for hospital system vendors and logistics infrastructure companies.

For 2026, KPMG is the agency to book first if your organisation’s critical processes sit on programmable logic controllers rather than web servers. Their OT assessment reports include segmented network architecture reviews, patch-level analysis of PLC firmware, and human-machine interface security checks — content that IT-only auditors cannot produce.

Best for: Utilities, port authorities, hospital groups, and logistics operators with OT/SCADA environments that need IEC 62443-aligned audit coverage.
