CSRO-Licensed VAPT & Penetration Testing Services Singapore

Vulnerability Assessment and Penetration Testing (VAPT) is  rigorous security evaluation used to identify and remediate weaknesses in your network and applications before they can be exploited by attackers. While a VA (Vulnerability Assessment) is a broad, automated scan that identifies potential security flaws, PT (Penetration Testing) involves manual engineering to find and exploit vulnerabilities to prove real-world risk. 

VAPT provides a clear, high-definition view of your security posture. By proactively identifying and fixing security gaps, you gain a deep understanding of your real-world risks and their potential business impact.

Beyond technical defense, VAPT is a critical component for regulatory compliance. It serves as documented proof of due diligence, providing the necessary reassurance to authorities, auditors, and stakeholders that your organization is committed to maintaining a robust and resilient security environment.

Penetration testing is categorized generally into 2 main apporaches:

• Black Box – Testing without any prior knowledge of the application, thus simulating a hacker attempting to breach a website over Internet
• Grey Box – Testing with limited knowledge of the application. Simulating an internal user or partner who has some internal access or knowledge

Yes, it is done at least once a year or after significant changes to the infra, applications or network.

This is due to the evolving threat landscape, frequent changes in the application, for compliance requirements, identifying security gaps and risk management.

The cost of a penetration test depends on the complexity of your system and the depth of testing required. Perennial offers three competitively priced  packages—Lite, Essential, and Enterprise—designed to fit everything from simple static websites to complex, high-compliance fintech / government platforms.

Lite: Best for static info-sites requiring basic compliance checkboxes.

Essential: Designed for SaaS platforms and apps handling PII and Customers data; focuses on Access Control and Logic flaws.

Enterprise: Likely required for MAS TRM or Singapore Government cybersecurity compliance. Includes API security, WAF bypass, and unlimited retests.

Our penetration tests are planned and coordinated to avoid any disruption. We will define engagement rules eg. scope, boundaries, mutually agreed schedule and will only start with your authorization. For best practice, we recommend our clients to target a test environment if possible or backup the data before pentesting.

A standard pentest in Singapore typically takes 2 days to 2 weeks, depending on the scope.

Lite assessments take 2–3 days, Essential tests take ~1 week, and Enterprise require ~2 weeks.

Our reports are designed to satisfy regulators like MAS and Singapore Government Agencies. Key components include:

• Executive Summary: High-level risk and assessment overview for Management / Regulators / Clients.

• Compliance Mapping: Findings linked to OWASP Top 10, CWE/CVE, and CVSS severity.

• Technical Proof-of-Concept: Detailed evidence for developers to reproduce and fix issues.

• Remediation: Clear, actionable guidance and advisory for closing security gaps.

A sample report is available upon request.

Yes. Many of our clients require yearly VAPT to satisfy regulatory or compliance requirements. To support our clients, we offer up to a 20% discount for repeat testing on the same application or environment, provided there are no major architectural or application changes.
