What are VAPT Testing Services?

VAPT (Vulnerability Assessment & Penetration Testing) services combine automated scanning with hands-on testing to provide a complete cybersecurity risk assessment.

Vulnerability Assessment (VA)

An automated process that scans IT systems and applications for known security flaws, misconfigurations, and outdated software. It identifies potential risks but does not test whether they can be exploited.

Penetration Testing (PT)

A controlled security test where ethical hackers simulate real-world cyberattacks, actively exploiting vulnerabilities to assess their impact. This hands-on approach uncovers security gaps that automated scans often miss.

Vulnerability Assessment & Penetration Testing (VAPT)

A combined approach where vulnerability assessments detect weaknesses, and penetration testing validates their exploitability—ensuring organizations understand both their risks and real-world attack scenarios.

Even when organizations implement regular security scans, the absence of in-depth penetration testing can leave significant gaps. 

Case study 

In the 2017 Equifax breach, attackers exploited an unpatched Apache Struts vulnerability, compromising the data of 147 million users. A vulnerability scan had flagged the issue, but no penetration test was conducted to check if it was exploitable. This oversight led to a $700 million settlement and severe reputational damage.

A well-executed VAPT strategy prevents such risks by combining real-world attack simulations with AI-driven threat detection. 

With the right cybersecurity partner, organizations can proactively identify, validate, and remediate vulnerabilities. AppSecure delivers comprehensive VAPT services, leveraging ethical hacking expertise and AI-driven threat detection to protect enterprises from potential cyber threats.

How VAPT testing works: Step-by-step process

A structured VAPT approach combines automated detection with manual testing to identify, validate, and remediate security vulnerabilities. This process is not just about running tools, it requires strategic execution to mimic real-world attack scenarios while ensuring minimal disruption to business operations.

Step 1: Scoping & planning

Every VAPT engagement starts with defining the scope, which includes identifying critical assets, assessing regulatory requirements (SOC2, ISO 27001, PCI DSS), and setting clear security objectives. 

Testing methodologies, whether black-box, white-box, or gray-box, are determined based on the organization’s needs. A poorly scoped test can either miss critical vulnerabilities or disrupt business operations.

Step 2: Vulnerability scanning

Security teams deploy automated vulnerability scanners like Qualys, Nessus, and OpenVAS to detect misconfigurations, outdated software, and unpatched vulnerabilities. 

While these tools provide a broad risk overview, they lack contextual awareness and often generate false positives. Without deeper validation, organizations risk either overlooking serious threats or wasting resources on non-exploitable issues.

Step 3: Penetration testing

Unlike automated scans, penetration testing involves manual exploitation of identified vulnerabilities to assess their real-world impact. 

Ethical hackers use Metasploit, Burp Suite, and Cobalt Strike to simulate targeted attacks on applications, networks, and cloud environments. 

This phase uncovers business logic flaws, authentication bypasses, and chained exploits that automated scans cannot detect. For example, in 2023, a misconfigured AWS S3 bucket led to the exposure of 3TB of sensitive data, an issue a vulnerability scanner alone would not flag.

Step 4: Reporting & remediation

A well-structured VAPT report prioritizes risks based on exploitability, business impact, and compliance requirements. Security teams receive an actionable roadmap with detailed remediation steps, patching strategies, and compensating controls. A CVE-based severity rating alone is insufficient, testers must provide real-world exploit scenarios to help organizations make informed decisions.

A well-executed VAPT engagement does not end with a report. Organizations must implement continuous security testing, integrating VAPT findings into DevSecOps pipelines and security policies to maintain long-term resilience.

Types of VAPT testing

Not all security threats originate from the same attack vector. Depending on an organization’s IT infrastructure, threat landscape, and compliance needs, VAPT services are tailored to assess vulnerabilities across networks, applications, cloud environments, and IoT systems.

1. Network Security VAPT

Network penetration testing identifies weaknesses in firewalls, VPN configurations, intrusion detection systems (IDS/IPS), and internal network segmentation. Unpatched network services, misconfigured security appliances, and outdated encryption protocols are common risk areas.

In 2021, an unpatched VPN flaw in Pulse Secure allowed attackers to infiltrate multiple government agencies and corporate networks, leading to nation-state-backed cyber espionage.

2. Web Application VAPT

Web applications are prime targets for cybercriminals, with SQL injection, cross-site scripting (XSS), and authentication bypasses among the most exploited vulnerabilities. This test simulates attacks on APIs, login mechanisms, session management, and input validation processes. 

3. Cloud Security VAPT

As businesses migrate to cloud platforms like AWS, Azure, and Google Cloud, misconfigured IAM policies, exposed S3 buckets, and insecure container deployments become major security concerns. 

Cloud VAPT identifies risks in cloud identity governance, storage access policies, and container orchestration environments to prevent unauthorized access and privilege abuse.

4. IoT & Mobile Security VAPT

The rapid adoption of IoT and mobile applications has introduced new attack vectors, with insecure firmware, default credentials, and weak encryption exposing businesses to large-scale threats. IoT & Mobile VAPT evaluates mobile app security, Bluetooth/Wi-Fi vulnerabilities, and firmware integrity to detect potential exploitation risks.

In 2023, a smart home security breach enabled attackers to exploit an insecure API, gaining access to security cameras, thermostats, and user data. A security audit revealed that insufficient authentication mechanisms allowed unauthorized API requests, highlighting the risks of untested IoT ecosystems.

Each attack surface requires a distinct approach. A layered, domain-specific VAPT strategy ensures that businesses protect their networks, applications, cloud environments, and IoT ecosystems against threats.

With AppSecure’s expert-driven VAPT services, businesses receive real-world attack insights, AI-driven threat detection, and proactive risk mitigation, ensuring security across their entire digital landscape.

Business benefits of VAPT testing

1. Prevent costly breaches by identifying real-world threats

Automated scans detect known vulnerabilities but often miss complex attack chains. Vulnerability Assessment and Penetration Testing (VAPT) combines automated assessments with simulated attacks to identify potential breach paths. Proactively addressing these vulnerabilities helps prevent financial losses, legal liabilities, and reputational damage.

2. Meet compliance requirements without gaps in security

Regulations such as SOC 2, ISO 27001, HIPAA, and CERT-IN mandate regular security assessments. While standard scans may overlook critical vulnerabilities, VAPT provides a comprehensive evaluation, ensuring full compliance and an improved security posture.

3. Secure third-party integrations and supply chains

APIs, cloud services, and third-party software expand the attack surface, introducing potential vulnerabilities. VAPT assesses both internal and external risk vectors, ensuring that dependencies do not compromise organizational security.

4. Reduce incident response costs with proactive security

The average global cost of a data breach reached $4.88 million in 2024, marking a 10% increase from the previous year. By identifying and addressing vulnerabilities before exploitation, VAPT can significantly reduce potential breach costs.

5. Strengthen security in development without slowing innovation

Integrating security into DevOps is crucial but shouldn't impede progress. VAPT integrates security testing into CI/CD pipelines, identifying exploitable flaws before code reaches production. This ensures both agility and security without slowing down development cycles.

By implementing VAPT, organizations can proactively address vulnerabilities, ensure compliance, and maintain a robust security posture in an evolving threat landscape.

How to Choose the Right VAPT Service Provider

Not all VAPT providers deliver depth, expertise, or actionable insights. Many rely solely on automated scans, missing business logic flaws and chained exploits. 

1. Choose a provider that combines manual and automated testing

Automated scanners can identify common vulnerabilities, but they often miss business logic flaws and complex attack chains. 

A strong VAPT provider should integrate automated scanning with human-led penetration testing to uncover deeper security risks. Ethical hackers can simulate real-world attacks, identifying weaknesses that tools alone cannot detect.

2. Provider with real-world security expertise

Many providers focus solely on meeting compliance standards like SOC 2, ISO 27001, or PCI DSS without assessing real-world attack scenarios. While compliance is essential, security teams must ensure their chosen provider goes beyond checkbox security and actively tests for exploitability. 

A robust VAPT provider should tailor assessments to an organization’s specific attack surface, using methodologies that mirror actual hacker techniques.

3. Detailed, exploit-driven reports with clear remediation steps

A VAPT report should do more than list vulnerabilities, it should demonstrate the real-world impact of each risk and provide actionable remediation guidance. 

Some providers generate automated reports with generic recommendations, offering little value to security teams. The right provider delivers reports that include proof-of-concept exploits, risk-prioritized fixes, and technical remediation steps tailored to the organization’s environment.

4. Proven expertise with security certifications and industry experience

Not all VAPT providers bring the same level of expertise. A provider should have experience in the organization’s industry and asset types, whether cloud infrastructure, APIs, mobile applications, or OT systems. 

Security certifications such as OSCP, CEH, CREST, or CISSP indicate a provider’s ability to conduct advanced penetration testing beyond basic vulnerability scans.

5. Provider offers retesting and long-term security support

VAPT is only effective if vulnerabilities are remediated and retested to ensure fixes are properly implemented. Some providers conduct assessments without offering follow-up validation, leaving security gaps unresolved. 

A strong VAPT provider should offer retesting, security advisory support, and customized testing approaches that evolve with emerging threats, ensuring continuous security improvements.
