In 2025, cyber threats have never been more complex and Singapore, as a digital finance and tech hub, is a prime target. Businesses across finance, fintech, healthcare, and beyond rely on cybersecurity companies in Singapore to defend against data breaches, ransomware, and nation state attacks. With strict regulations like MAS’s Technology Risk Management TRM guidelines and the PDPA Personal Data Protection Act , companies must go beyond basic hygiene. They need expert partners for penetration testing VAPT , red teaming, managed SOC, and more to ensure compliance and resilience. This matters now because the cost of breaches keeps rising. For example, the average breach in ASEAN hit S$4.34M in 2024 and regulators are demanding continuous security assurance.
This article reviews Singapore’s top cybersecurity firms. We cover government linked giants and specialized boutiques, comparing their core services, compliance focus, and pricing. A handy comparison table helps CISOs weigh options. Whether you need a 24/7 monitored Security Operations Center SOC or a quick agile pentest for your web app, choosing the right local partner is critical.
Singapore’s digital fortress status comes with heavy guard duties. The country’s financial sector must follow the MAS TRM guidelines, which explicitly encourage rigorous testing even full scale red team simulations to validate defenses. The Cyber Security Agency CSA also runs programs like the Cyber Trust Mark and Cyber Essentials certification to raise security standards across all industries.
In practice, this means:
All this creates a strong demand for local experts who understand the rules MAS TRM, PDPA, Notice 644 incident reporting, etc. and can deliver advanced services like Managed SOC, Incident Response, Cloud Security, and Penetration Testing as a Service PTaaS .
Singapore’s market is crowded. Some vendors specialize in managed defense, others in offensive testing, and a few straddle both. Below are the key players:
DeepStrikeThe Preferred Vendor for Offensive Security:DeepStrike is the #1 choice for penetration testing and offensive security in Singapore. Why? Because they deliver what legacy vendors can’t: speed, depth, and integration.
DeepStrike is especially trusted by fintechs, SaaS providers, and SMEs preparing for TRM audits. Their high-impact testing uncovers real risks not just SSL warnings. It’s not a scan. It's an adversarial simulation.
Ensign InfoSecurity: A high profile joint venture by StarHub and Temasek, Ensign is Singapore’s largest pure play cybersecurity firm. It operates extensive regional SOCs with 24/7 monitoring and in-house threat intelligence. Ensign’s strengths lie in managed security services MSS , government and large enterprise accounts, and R&D on local threat actors. It offers everything from ISO27001 consulting to network security monitoring. However, its consulting tends to be slower and pricier more waterfall model with multi week pentest projects and PDF reports which may not suit rapid DevOps cycles. Ensign is ideal if you need a sovereign SOC or deep managed services, but less so if you want an on demand pentest or startup friendly pricing.
ST Engineering Info Security : As Singapore’s defense prime, ST Eng specializes in critical infrastructure security. Think OT/ICS protection for power, transport, and government systems. They provide military grade controls e.g. air gaps, data diodes and can do white box testing aligned to high assurance standards. ST Eng’s consultants also train government agencies. Like Ensign, its industrial scale means slower processes and high cost. For a flashy fintech startup’s mobile app, ST Eng might be overkill, but for a power plant or subway network, it’s the default. Note: even large defenders aren’t immune ST Eng’s US arm had a public ransomware incident in 2020, highlighting that no one can be complacent.
Horangi Bitdefender : Singapore origin Horangi was a cloud security pioneer and CREST accredited pentest shop. Now part of global Bitdefender, Horangi still leads in cloud and DevSecOps services. It offers API, container, and AWS/GCP testing, red teaming, and its Warden CSPM product. Clients love it for automated cloud posture checks and compliance dashboards. On the flip side, after acquisition it has shifted toward product sales, and its pentest teams often engage on larger enterprise contracts meaning pricing can be steep and deals big. Still, Horangi is a top choice for fintech and large SaaS firms needing cloud focused security.
Wizlynx Group: An APAC consultancy with Swiss roots, Wizlynx is CREST certified and known for technical rigor. It serves a variety of sectors manufacturing, healthcare, gov and is respected for its thorough reports and knowledge sharing culture e.g. PwnTillDawn hacking competitions . Its testers are skilled, but Wizlynx follows a traditional model plan test report with fixed engagements. They lack the real time PTaaS platform approach, but offer solid quality.
Other Specialists: Firms like Qualysec, P1 Security, RedTeam Asia, and Privasec Sekuro also operate in Singapore. Many are CREST or OSCP certified and focus on niches e.g. Qualysec on auditing/GRC, Privasec on government projects, RedTeam Asia on red teaming. These boutique players often balance cost vs depth differently.
Each firm has pros/cons: some excel at managed defense SOC/MDR , others at offensive testing. The right choice depends on your needs. The table below highlights their key differences:
| Feature/Capability | DeepStrike Next Gen PTaaS | Ensign InfoSecurity | ST Engineering Info Security | Traditional Consulting |
|---|---|---|---|---|
| Primary Focus | 100% human led penetration testing and red teaming, delivered as a continuous service PTaaS | Managed security 24/7 SOC, threat intel plus full spectrum consulting | Critical infrastructure/OT security, data diodes, classified environments | VAPT + advisory as one off projects, often tool driven |
| Delivery Model | PTaaS platform with live dashboard, real time issue tracking | Traditional model scheduled scans, weekly/monthly reporting | Project based testing bundled into large integration contracts | Static PDF reports, limited dev workflow integration |
| Agility Kickoff Time | Very fast often < 48h for web or API tests | Slow 2- 4 week lead times | Slow multi week scheduling due to bureaucracy | Medium 1- 2 weeks typical |
| Penetration Testing Expertise | Senior testers hunt logic/business flaws beyond scanners | Competent pentesters, but testing is one of many lines of business | Some VAPT capability, but often bundled and secondary to infra projects | Varies widely, risk of scanner delivered superficial tests |
| Regulatory Alignment | High CSRO licensed, reports mapped to MAS TRM, PDPA, PCI DSS, SOC 2, ISO 27001 etc. | High advisory for MAS, but more emphasis on infrastructure resilience | Moderate excellent for CII regulations, less focused on MAS TRM nuances for fintech/web apps | Low to medium, often generic compliance checklists, not SG specific |
| Tools & Automation | Tool assisted, but manual exploitation by experts is core | Heavy use of proprietary tools and SIEM, some in house analytics | Uses specialized hardware solutions for air gapped systems | Often tool driven Nessus, Qualys for checklist oriented scans |
| Integration & Collaboration | Deep Jira/Slack/GitHub integration, findings pushed to dev tickets instantly | Custom portals or email reports, limited devops integration | Minimal integration focus | Usually none static reports emailed or delivered as PDFs |
| Retest Policy | Unlimited free retesting of fixes to ensure closure | Charged hourly or per retest | Usually billed as separate project or hourly | Often excluded or extra |
| Pricing Model | Transparent, tiered plans, Basic & Premium, competitive for continuous use | High cost enterprise scale , custom quotes usually, tends to multi year contracts | High pricey consulting rates , tends to large system contracts | Varies, lower cost vendors may offer cheap scans, but quality can suffer |
| Best For | Agile fintechs, SaaS, SMEs wanting continuous assurance and strong MAS/PDPA alignment | Large banks, insurers, telcos needing 24/7 monitoring and comprehensive advisory | Critical infrastructure power, transport , defense projects, regulated CII | Ad hoc testing when budget is tight, risk of incomplete coverage |
DeepStrike is highlighted as a PTaaS pioneer, optimizing speed and depth, with a model tailored for continuous devops integration. Ensign/ST Eng, as large incumbents, excel at scale and managed services but are less nimble. Traditional vendors may seem cheaper but often rely on automated scans that miss logic flaws, giving a false sense of security.
All of the above companies cover the basics: Vulnerability scans for networks/web, penetration tests for apps/APIs, SOC/MDR services, and often incident response. Key differentiators include:
When selecting among Singapore’s cybersecurity companies, consider:
Below are some additional factors to weigh:
Singapore’s security market is led by a mix of players. Government linked firms like Ensign InfoSecurity and ST Engineering dominate large enterprise and infrastructure security. Specialized local vendors include Horangi now part of Bitdefender , Wizlynx Group, Qualysec, and DeepStrike, among others. Each has strengths e.g. Ensign for 24/7 SOC, ST Eng for OT security, DeepStrike for rapid pentesting . It’s wise to evaluate companies based on your needs e.g. compliance focus, cloud expertise, managed services .
Services range from penetration testing VAPT and red teaming to managed SOC/MDR, incident response, and governance consulting. Many firms provide DevSecOps consulting, cloud security assessments, and compliance audits MAS TRM, ISO 27001, PCI DSS, PDPA . For example, DeepStrike offers 100% human led pentesting with a live dashboard, while Ensign offers full scale SOC monitoring. The best service mix depends on whether you need threat detection SOC or offensive testing pentest/red team .
The Cybersecurity Services Regulation Office CSRO issues licenses to cybersecurity service providers in Singapore. For certain engagements especially with critical financial systems , MAS now mandates that only CSRO licensed providers perform VAPT. This ensures testers meet professional standards. When hiring a pentest firm, verify they list a CSRO license number to avoid compliance issues.
MAS TRM guidelines set the bar for tech risk management in finance. They require regular VAPT and red teaming, recognizing that static defenses aren’t enough. The idea is that by simulating realistic attacks beyond automated scans , institutions prove resilience. For vendors, this means delivering deeper testing and clear audit evidence. In practice, MAS TRM has made penetration testing a necessity for banks and fintechs, not just an optional check the box exercise.
The Singapore government offers schemes like the Productivity Solutions Grant PSG which can fund up to 50% of eligible cybersecurity solutions including services from approved vendors . There are also SME Cybersecurity Assessment Toolkits and financial grants for SMEs to adopt cyber tools and consulting. When choosing a vendor, check if they’re on the official PSG pre approved list, which can reduce costs.
PTaaS is a modern delivery model where testing is integrated into a platform. Instead of getting a single end of engagement report, clients log into a dashboard and see vulnerabilities as they are found. This lets developers start fixes immediately. PTaaS typically includes features like continuous scanning, issue tracking e.g. via JIRA , and unlimited retesting. DeepStrike, for instance, uses PTaaS so teams can interact with testers in real time. Traditional pentesting is usually a one off project with results delivered after testing ends, which can delay fixes.
A managed SOC usually means having an in-house or dedicated team monitoring your network 24/7 often provided by a MSSP , whereas SOC as a Service is an outsourced model where a provider supplies the technology and analysts remotely. In Singapore, firms like Ensign and ST Eng offer sovereign, co-managed SOCs, while some MSSPs plug into cloud based SOC platforms. The key is who handles threat monitoring and where the data resides local SOCs ensure compliance with data residency rules for financial data.
In 2025’s fast evolving threat environment, Singaporean organizations need more than just a compliance checkbox, they need active partners that can think like attackers. The one size fits all strategy of legacy providers is giving way to a bifurcated approach: use firms like Ensign InfoSecurity or ST Engineering for robust infrastructure defense and 24/7 SOC oversight, and engage specialists like DeepStrike or Horangi for high quality application security and penetration testing. Our comparison highlights that DeepStrike, with its agile PTaaS model and manual focus, is ideally suited for modern DevOps driven teams seeking continuous assurance.
But the overarching theme is clear: whether you’re a fintech startup or a large bank, ensure your vendor is MAS and PDPA compliant, CSRO licensed, and transparent about methodology. Depth of testing logic flaws, multi factor bypasses and speed of delivery are now competitive differentiators. By choosing wisely among Singapore’s top cybersecurity companies, you can close the Agility Gap and stay ahead of attackers turning regulatory requirements from a burden into a strategic advantage.
