Why VAPT Matters Now
Vulnerability Assessment: Breadth & Coverage
- A vulnerability assessment gives you a comprehensive view of security weaknesses across your computers, systems and networks. Using automated scanners, we can evaluate your environment against tens of thousands of known vulnerabilities and misconfigurations.
- These assessments are essential to meet standards such as PCI DSS, FFIEC and other regulatory and industry frameworks. Scans can be run on-demand or scheduled, often completing in minutes to a few hours depending on scope.
- The output: a clear, prioritised list of vulnerabilities. The challenge: knowing which ones really matter and how an attacker could chain them together. That’s where penetration testing comes in.
Penetration Testing: Depth & Exploitation
- Penetration testing simulates a determined attacker. Our certified ethical hackers go beyond checklists and scanners to actively exploit weaknesses and demonstrate real business impact.
- Using techniques such as password cracking, buffer overflows, SQL injection and abuse of business logic, we attempt to compromise systems and extract data in a controlled, non-destructive manner.
- The result is a practical, evidence-backed view of where, how and to what extent your organisation can be breached – and what to do about it before a real attacker gets there first.
Key assurance
All exploit work is performed by senior OSCP / CEH-certified testers, following strict rules of engagement.
Our VAPT Methodology
Our approach follows a structured, repeatable methodology built around four core stages. This ensures each engagement is thorough, transparent and aligned to your risk and compliance needs.
Scoping
1. Information Gathering & Planning
We begin by understanding your objectives, risk appetite and scope of work. This includes defining in-scope networks, applications, APIs, cloud services and data.
- Work with your team to define clear goals and success criteria.
- Select the right type of test (black-box, grey-box, white-box).
- Perform reconnaissance on hosts, domains and infrastructure (e.g. Nmap, Nessus, DNSENUM, DNSMAP, LBD).
- Map the attack surface and identify potential entry points.
Analysis
2. Vulnerability Detection & Security Posture Review
Next, we evaluate how your applications, servers and controls respond to targeted probing. This includes automated and manual testing techniques.
Application Security Testing
- SAST (Static Application Security Testing) : Deep analysis of source, bytecode or binaries to find insecure coding patterns and design flaws, using tools such as HP Fortify.
- DAST (Dynamic Application Security Testing): Probing running web and mobile applications in staging or test environments using tools like Burp Suite, Acunetix and Netsparker.
- For mobile apps, we leverage APK tools, simulators, emulators and targeted manual scripts to surface runtime issues.
Infrastructure & Configuration Review
- Server Hardening : We assess patching, services, file permissions, password policies and network ports against best practices and hardening benchmarks.
- Privilege & Access Review : Evaluate privileged admin and user access, SSO, role design and access management. Benefits include improved visibility, compliance, productivity, integrated access control and reduced malware/insider risks.
- Data Encryption : Review encryption at rest (databases, disks, backups, cloud storage) and in transit (TLS, APIs, internal traffic) to protect sensitive and personally identifiable information.
- Backup & Retention Policies : Analyse how often you back up, what you retain, and how you store, protect and restore backups in line with legal, privacy and business requirements.
Attack
3. Weakness Exploitation & Maintaining Access
In this stage, we act like an attacker – but with rules of engagement that protect your systems and data. We use a combination of commercial tools and custom scripts to exploit validated weaknesses.
- Web application attacks such as broken authentication, SQL injection, file upload abuse and backdoors.
- Privilege escalation attempts to move from low-level to admin access.
- Establishing controlled “persistent access” to mimic what a real attacker would do after initial compromise.
The goal is not just to prove that a vulnerability exists, but to show the true impact: what data could be accessed, what systems could be controlled and how long an attacker could remain undetected.
Remediate
4. Reporting, Remediation & Retesting
We finish with a comprehensive report and a remediation-focused review. Our aim is to make vulnerabilities understandable and actionable for both technical and non-technical stakeholders.
Our Reports Include:
- Executive Summary : Business-level overview of risk, key findings and overall posture.
- Validated Exploits: Step-by-step examples of exploited weaknesses, including request/response samples where appropriate.
- Weakness Classification : Aligned to risk severity and common standards (e.g. OWASP, CVSS).
- Remediation Guidance : Practical recommendations for fixing each issue and strengthening your security architecture.
We remove false positives from automated tools and can collaborate with your teams on remediation plans. Optional retesting validates fixes and updates risk scores.
Only Certified, Senior Penetration Testers on Your Engagement
Cyber security testing is only as strong as the people behind it. That’s why every ComplySec360 VAPT engagement is led and executed by OSCP and CEH-certified penetration testers with real-world experience across complex enterprise environments.
OSCP-Certified
Offensive Security Certified Professionals
- OSCP testers are trained to think and act like real attackers. They specialise in proving exploitability, pivoting through networks and uncovering chained attack paths — not just reporting scanner output.
CEH-Certified
Certified Ethical Hackers
- CEH-certified professionals bring a broad, methodical understanding of attack techniques across web, infrastructure, cloud and applications, ensuring full-spectrum coverage of your environment.
Experience-Driven
No Juniors “Learning” on Your Systems
- We do not staff untrained or junior resources on your engagement. Your environment is tested by seasoned professionals who understand both the technical details and the business impact of each finding.
- This approach is especially important if you rely on VAPT results for compliance (SOC 2, ISO 27001, PCI DSS) and cyber insurance underwriting — you need findings you can trust.

Frequently Asked Questions
Remove Vulnerabilities from your environment and protect from cyber attacks.
No. Pen testing and vulnerability scanning are two very different ways to test your systems for vulnerabilities.
Penetration testing and vulnerability scanning are often confused for the same service. A vulnerability scan is an automated, high-level test that looks for and reports potential vulnerabilities. A penetration test is a detailed hands-on examination (intrusive) by a real person that tries to detect and exploit weaknesses in your system.

A penetration test is a detailed hands-on examination (intrusive) by a real person that tries to detect and exploit weaknesses in your system.
Vulnerability scans assess computers, systems, and networks for security weaknesses, also known as vulnerabilities. These scans are typically automated and give a beginning look at what could possibly be exploited. A good vulnerability scan can search for over 50,000 plus vulnerabilities and are required as per PCI DSS, FFIEC, and other regulations.
Vulnerability scans can be performed manually or run on a scheduled basis. It will complete in as little as few minutes to as long as several hours depending on the assets being scanned. Vulnerability scans don’t go beyond reporting on vulnerabilities that are detected.

A penetration test simulates a hacker attempting exploit vulnerabilities to get into a business system.
An certified pen tester, often called ethical hackers, search for vulnerabilities and then try to prove that they can be exploited. Using methods like password cracking, buffer overflow, and SQL injection, they attempt to compromise and extract data from a network in a non damaging way.
