11 Best Cybersecurity Companies in Singapore (2026)

Cybersecurity in Singapore covers everything from round-the-clock security operations centres to focused penetration-testing outfits, threat-intelligence shops and incident-response specialists, and the right fit depends on what you actually need protected. The providers below are established, currently-operating firms with a genuine Singapore presence, spanning managed security services, penetration testing, SOC monitoring, threat intelligence, incident response and governance, risk and compliance (GRC) work. Penetration testing and managed SOC monitoring are licensed activities under Singapore's Cybersecurity Act, so check a shortlisted provider's current licence and certifications directly with them. Treat this as a starting shortlist to research further, not a fixed ranking.

Ensign InfoSecurity is a pure-play cybersecurity services firm formed in 2018 when Temasek and StarHub merged their respective security units, StarHub's Cyber Security Centre of Excellence and Accel Systems & Technologies, with Temasek-owned Quann, formerly known as e-Cop. Headquartered in Singapore, it says it now fields around 1,000 cybersecurity professionals across the region, covering managed security services, a 24/7 security operations centre, penetration testing and red teaming, incident response, threat intelligence and cybersecurity advisory and GRC work. The firm has also been developing newer capabilities such as an in-house, AI-assisted security operations centre. Its scale and breadth suit larger organisations that want most cybersecurity needs handled by one regional provider.

NCS is a large, Singapore-headquartered technology group, part of the Singtel group, whose cybersecurity arm is a licensed provider under Singapore's Cybersecurity Act for both penetration testing and managed security operations centre monitoring. Its cyber practice spans security operations centre services, consulting and advisory across infrastructure, applications, cloud and DevSecOps, governance, risk and compliance, enterprise and cloud security architecture, and security testing and systems hardening. NCS says its cybersecurity business draws on decades of the wider group's history and a dedicated team of several hundred specialists across the region. Its size and breadth suit larger enterprises and government-linked organisations wanting an integrated security practice alongside broader IT and systems-integration work, rather than a small boutique specialist.

Vantage Point Security is a Singapore-founded offensive-security specialist, set up in 2014 and now also running offices in Jakarta and Bangkok. It focuses solely on CREST-accredited penetration testing and application-security testing, delivered by a team it says numbers more than 50 CREST-registered consultants working as full-time staff rather than contractors, across web, mobile, API, network, cloud, Active Directory and IoT and hardware targets. A co-founder was an original author of OWASP's mobile testing standards, MASTG and MASVS, and the firm publishes some of its own testing research and audit methodology publicly. It describes itself as a pure offensive-security firm rather than an MSSP or Big Four-style audit practice, which suits buyers who specifically want a dedicated pentesting partner.

Wizlynx group is a Swiss-founded cybersecurity provider with an operating presence in Singapore, where it is licensed by the Cyber Security Agency and the Cybersecurity Services Regulation Office for penetration testing, and has held CREST accreditation since 2017. Its offensive-security line covers vulnerability assessments, penetration testing, red teaming, social-engineering exercises, cloud assessments and secure-code reviews, plus IoT and industrial-control-system testing, while its defensive side covers threat intelligence, security-awareness training, security-operations-centre management, system hardening, managed services, incident response, and compliance and governance consulting. The firm markets itself under the line 'Swiss precision, global protection,' and its combination of a global network with local Singapore licensing may suit businesses that also operate or hold compliance obligations elsewhere.

Privasec is a cybersecurity firm incorporated in Singapore in 2018, with an office at International Plaza on Anson Road, and is licensed by Singapore's Cybersecurity Services Regulation Office for both penetration testing and security-operations-centre services. It became part of the Australian Sekuro group but continues to operate under the Privasec name in Singapore. Its work spans governance, risk and compliance advisory, including ISO 27001 and ISO 27701 implementation and PCI DSS support, alongside offensive-security testing such as penetration testing, red teaming and cloud-security assessments, plus managed security services and specialist team augmentation for in-house security functions. Its compliance depth makes it a reasonable option for regulated businesses that want GRC advisory alongside technical testing, under one roof.

Swarmnetics is a Singapore-based cybersecurity firm founded in 2015 by industry veterans, operating from Robinson Road with an additional office in Brunei. It is CREST-accredited and licensed by Singapore's Cyber Security Agency for penetration testing, and says it also holds ISO/IEC 27001 certification. Its work covers infrastructure testing such as network, wireless and IoT penetration testing and vulnerability assessments; application security across web, mobile, API and, more recently, LLM applications, plus secure code review; cloud-security assessments; and adversarial simulations such as phishing, red-team and purple-team exercises. The firm says it has worked with more than 200 clients across sectors including financial services, government and healthcare, making it a mid-sized, technically focused alternative to the larger MSSPs.

STAR Labs SG is a Singapore-incorporated offensive-security firm that positions itself as a research organisation first and a consultancy second. Its team has won the Master of Pwn title at Pwn2Own twice and holds vulnerability credits from Microsoft, Google, Apple, Oracle and Samsung, and the firm says that research feeds into its paid engagements. Commercially, it offers product-security audits and red-team engagements across kernel and hypervisor security, browser and runtime security, firmware and embedded systems, cloud and container infrastructure, and AI security, and is licensed in Singapore for penetration testing. It's a narrower, more technical option than the generalist MSSPs, best suited to organisations building software or hardware products that want assessors who also carry out original vulnerability research.

Firmus is a cybersecurity firm established in 2008 that is headquartered in Malaysia and maintains an established Singapore office serving the local market. It is CREST-accredited for penetration testing, and its service range covers vulnerability assessments and penetration testing, managed detection and response, incident response and digital forensics, security consulting, compliance assessments, security-awareness training, and a dedicated operational-technology security practice. The firm positions itself as aiming to be a long-term cybersecurity partner rather than a one-off vendor, and its OT and industrial-systems work in particular may appeal to manufacturers and infrastructure operators in Singapore that need testing and response capability beyond standard office IT. As with any regional provider, ask specifically which work is done by the Singapore-based team.

Blackpanda is a Singapore-based cyber incident response specialist founded by a team that includes former US Army Special Forces personnel, with regional hubs also in Tokyo, Hong Kong and Manila. Rather than only billing by the hour, it sells IR-1, a fixed-cost subscription that bundles 24/7 emergency incident-response dispatch with continuous attack-surface scanning and access to Lloyd's of London-underwritten cyber insurance, alongside traditional incident-response consulting, digital forensics, ransomware-negotiation support, compromise assessments, and incident-response preparation such as tabletop exercises and threat hunting. Blackpanda has also signed a partnership with Singapore's Cyber Security Agency aimed at strengthening cyber emergency response in the country. It's a specialist choice for businesses that want a ready-made incident-response plan in place before, not after, a breach.

Athena Dynamics is a Singapore-based cybersecurity consultancy established in 2014 as the pure-play cybersecurity arm of BH Global, and it says it operates independently of any state-level relationship. Its focus is on IT and operational-technology protection for critical infrastructure, including detection-less content sanitisation, binary code review, zero-trust micro-segmentation, data-diode-based network separation, maritime cybersecurity and digital forensics, alongside more conventional risk assessment, security monitoring and incident-response planning. It also runs 'The Good Hackers' Alliance,' its ethical-hacking and penetration-testing arm. The firm says it has completed several hundred critical-infrastructure-protection projects and worked with well over a hundred organisations in the region since it started. Its OT and critical-infrastructure specialism sets it apart from generalist MSSPs, and suits industrial, utilities and infrastructure operators.

CYFIRMA is a Singapore-headquartered cybersecurity firm, founded in 2017 by Kumar Ritesh, that focuses on threat intelligence rather than hands-on testing or monitoring. Its platform, marketed under names such as DeCYFIR and DeTCT, combines external attack-surface discovery, vulnerability intelligence, and brand and digital-risk protection with what it describes as predictive, 'outside-in' threat intelligence meant to flag likely attacks before they happen, backed by an analyst team rather than software alone. The company has grown into a global operation with offices across Asia, the US, Europe and the Middle East. It suits security or risk teams that want an ongoing intelligence feed on who is targeting them, layered on top of whatever defensive tooling and testing they already use.
