Risk-Based Manual Exploitation

We prioritise what matters – Exploitable risks in your most critical functions – giving you confidence what matters most is protected

What is VAPT and How Do We Approach It?

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.

 At Perennial, we typically use two main approaches to provide the most realistic simulation of an attack:

Black-Box Testing (Zero Knowledge):

Testing without any prior knowledge of the application or system, thus simulating a hacker attempting to breach a website or network over the Internet. Best for testing your external defenses to a real-world attacker. You do not need to provide any information other than the target domain or IP addresses.

Grey-Box Testing (Partial Knowledge):

Testing with limited knowledge of the application or system, simulating an internal user or partner who has some internal access or a compromised account. Best for identifying Business Logic Flaws or Lateral Movement risks. You provide us with basic user credentials, VPN access or high level architectural overviews etc.

 

How to Choose the Right VAPT for Your Business?

Choosing the right VAPT can be confusing, especially with technical variations like Network, Web, API, or Mobile Penetration Testing. 

The most efficient way to scope your project is to align it with your Business Type and your Current Security Situation.

1) By Your Business Model (The Environment)

Network VAPT: Best if you operate a physical office, manage local servers, or have complex internal systems. We focus on “crown jewels” like Active Directory (AD), ERP systems, and SQL databases where credentials and confidential information are stored,  and most of the time, unpatched or running outdated software.

Application VAPT (Web/API/Mobile): Essential if your business is your digital product (e.g., SaaS, E-commerce, or FinTech portals). We perform deep-dive manual testing to find Business Logic Flaws like Broken Access Control and Privilege Escalation where stolen or misused customer credentials can lead to devastating reputational damage and legal liabilities.

 2) By Your Current Situation (The Goal)

  • “We need to meet Client or Regulatory requirements eg. MAS TRM”: Network or Application Grey-Box Penetration Test. Most high-compliance frameworks require “Authenticated” testing. We simulate a user with standard access to verify that your internal permissions, data encryption and  access token etc meet the rigorous standards expected by auditors and enterprise partners.
  • “We recently had a security scare or a minor breach”: Network Grey-Box Penetration Test. We simulate a “compromised user” scenario to see how far an attacker can move laterally through your network and what credentials or information can be accessed.
  • “We handle sensitive customer data (PII) or IP”: Application Grey-Box Penetration Test. This ensures compliance with PDPA and protects your reputation against data exfiltration.
  • “We have some publicly accessible hardware or nodes, such as kiosk”: Network Black-Box Penetration Test. This simulate an attacker attempting to “break out” of the restricted kiosk environment or exploit exposed network ports to gain unauthorized access to your backend servers or central management system.
  • “We have an Internet facing application with no self-registration and we want to test our ‘Front Door’ defenses”: Application Black-Box Penetration Test. We focus on your unauthenticated attack surface, simulating a targeted attack to check if your portal is vulnerable to credential stuffing, MFA bypass techniques, or brute-force attempts that could lead to an unauthorized breach.

FAQ's

Penetration testing is categorized into 3 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
  • White Box – Testing with full knowledge of the application, simulating an internal threat with access to source code and other sensitive information. Often for internal security team review.

A Vulnerability Assessment is a broad, automated scan that identifies potential security flaws, while a Penetration Test is a manual, targeted exploitation of those flaws to verify their real-world impact. While VA is “broad and shallow,” PT is “deep and rigorous.”

Our service includes both to ensure complete coverage.

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.

Yes, we offer a free evaluation where we identify first vulnerability without providing a detailed report.

This service is for customer considering Enterprise package. This allows you to understand the value of our services and see the potential security improvements.

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.
