In the digital age, organisations are exposed to numerous cybersecurity threats that can compromise confidential information, disrupt operations, and damage brand reputation. Implementing robust security measures is essential to protect digital assets and ensure business continuity.
Compliance with security standards and regulations is crucial, but it’s equally important to go beyond mere compliance by continuously identifying and mitigating security threats. Vulnerability Assessment and Penetration Testing (VAPT) is a key component of a comprehensive cybersecurity strategy that helps organisations achieve this goal. Penetration testing, in particular, simulates real-world attacks on an organisation’s IT systems and infrastructure. In these tests, professional ethical hackers attempt to exploit vulnerabilities to gain unauthorised access and perform potentially destructive actions, thereby identifying weaknesses before malicious actors can exploit them.
VAPT helps assess the level of risk and exposure an organisation faces from cyberattacks and provides recommendations for improving security posture and resilience. VAPT is not only a requirement for compliance with various standards and regulations such as PCI DSS, HIPAA, ISO 27001, SOC 2, GDPR, and Digital Personal Data Protection (DPDP) but also a vital component of a proactive and holistic approach to organisational security.
VAPT Testing Steps and Process
VAPT comprises two primary phases: vulnerability assessment and penetration testing. In the vulnerability assessment phase, the target environment is scanned and analysed for potential vulnerabilities, such as misconfigurations, outdated software, weak passwords, and unpatched systems. The penetration testing phase simulates real-world attacks on the target environment, using the same tools and techniques as malicious hackers to exploit the identified vulnerabilities and evaluate the effectiveness of existing security controls.
The VAPT process typically follows these steps:
- Scope definition:
The scope of the VAPT project is defined, encompassing the objectives, scope, boundaries, and limitations of the testing. This scope should cover all relevant assets and components of the target environment, such as networks, servers, applications, databases, and endpoints. It should also specify the type and level of testing, such as black-box, grey-box, or white-box, along with the expected deliverables and timelines.
- Information gathering
The VAPT team gathers as much information as possible about the target environment, including domain names, IP addresses, network topology, operating systems, software versions, and user accounts. This information helps identify the attack surface and potential entry points for testing. The information-gathering phase may involve both passive and active reconnaissance, such as DNS enumeration, OS fingerprinting, service discovery, and banner grabbing.

- Vulnerability scanning
The VAPT team uses tools and techniques to sweep across the target environment and look for vulnerabilities and the VAPT process involves use of auto scan tools, manually as well as code review. This phase may require a range of network scans such as network, host, application and/or database scans that can be either authenticated or unauthorised, and may be either a complete or partial scan. The findings of the vulnerability scans are checked and ranked according to the threats of risk, harm, or being exploited.
- Penetration testing
The next step employed by the VAPT team involves using various tools and techniques including social engineering, phishing, brute force attacking, SQL injecting, cross-site scripting, and buffer overflow on the vulnerabilities discovered during the scanning. The penetration testing phase may include different categories of attacks and type of attacks like web, wireless, network, physical, social engineering attacks and scenarios may be like insider, outsider, both. The findings of the penetration testing conducted are then reviewed and evaluated for the effects or losses that have be experienced by the system, as well as to determine causes of vulnerabilities exploited by the test and possible preventive measures.
- Reporting and remediation
After an assessment, the VAPT team synthesises a report encompassing the assessment’s overview, objectives, method, results, proofs, and the severity levels of vulnerability and exploitation. The report provides specific and prioritised recommendations for the organisation to remediate the identified security issues and improve the organisation’s security status. Moreover, the discovered vulnerabilities can be communicated to the organisation and help during the remediation process as well as repeat the test to ensure the efficiency of the fixes of the vulnerabilities.
VAPT Testing Tools
There are various tools and frameworks available for conducting VAPT, depending on the type, scope, and complexity of the testing. Some of the common tools and frameworks are:
- Network Mapping and Port Scanning Utilities: Identify hosts, services, and vulnerabilities, with features like OS detection, version identification, and service enumeration, including script execution.
- Penetration Testing Frameworks: Automate exploiting vulnerabilities, offering post-exploitation capabilities, high adaptability, and integration with various tools for payloads, modules, and exploits.
- Web Application Security Testing Tools: Intercept HTTP requests, analyse responses, detect, and exploit vulnerabilities like SQL injection, cross-site scripting, and session hijacking effectively.
- Network Protocol Analysers: Capture and examine network traffic, identify anomalies, errors, malicious activities, provide filtering, decoding, and support for various protocols comprehensively.
- Vulnerability Scanners: Scan and audit network, system, and application vulnerabilities, generate comprehensive reports, assisting in prioritising effective remediation efforts efficiently.
- Database Security Assessment Tools: Identify DBMS vulnerabilities, analyse access controls, encryption mechanisms, ensuring data integrity, and sensitive data protection proficiently.
- Cloud Security Assessment Tools: Assess cloud infrastructure security, identify misconfigurations, insecure APIs, and data exposure risks, ensuring resource confidentiality, integrity, and availability effectively.
- Malware Analysis Tools: Analyse and dissect malicious software, identifying behaviour, functionalities, and vulnerabilities, aiding in threat detection and mitigation strategies.
- Reverse Engineering Frameworks: Unravel software code and binaries, understanding their functionality, vulnerabilities, and potential exploits, aiding in security assessment and patch development.
- Password Cracking Tools: Employ brute-force or dictionary attacks to assess password strength, identify weak credentials, and strengthen authentication mechanisms for enhanced security posture.
- Threat Intelligence Platforms (TIPs): Aggregate and analyse threat data, proactively identify emerging threats, prioritise vulnerabilities, and enhance incident response capabilities significantly.
- Red Team Tools and Frameworks: Simulate cyber-attacks, test security defences, conduct sophisticated attacks, emulate adversary tactics, techniques, procedures, providing actionable insights for security posture improvement.
VAPT vs. Traditional Security Measures
In this regard, VAPT is not a substitute for the basic security measures such as firewalls, antivirus, encryption, backup and other physical and technical controls but an augmentation of them. Although the regular security controls create initial layers of security, they might not be enough to counter the new and complex risks. VAPT is more practical and presents a better picture of an organisation’s security by mimicking what hackers are capable of doing in the course of an attack and the overall gaps and risks involved that other approaches might not expose. Moreover, it comes with practical guidance and details on how the organisation under test can be made more secure.
What Are The Benefits of VAPT for Tally?
VAPT provides numerous advantages for Tally & its subsidiary entities, such as:
- Enhanced security: VAPT assists in pointing out the security vulnerabilities and faults in the organisational network, systems, applications, as well as data and ensuring that the organisation’s network, systems, applications and data are duly secured from cyber threats. VAPT also assists in verifying and enhancing the best practices of the existing security controls and the policies as well as identifying and managing new and complex security threats.
- Improved Compliance: Helps to stay compliant with the standards involving, for example, PCI DSS, HIPAA, ISO 27001, and GDPR to avoid fines and showcase the constant and proper security assessment.
- Customer Confidence: Increase customer confidence through better security management that minimises the cases of data compromises and frauds hence increasing customer satisfaction.
- Risk Management: Reduces chances of risks being exploited hence a secure operation environment is observed before any vulnerability is exploited.

- Reduced Costs: The earlier potential security weaknesses are detected, the lower the costs of security breaches for a business; tailors security budgets and proposes efficient solutions to solve most pertinent problems at a reasonable cost.
- Continuous Improvement: Reduced risks that stem from outdating security measures by integrating a continuous process of testing of the announced security features and giving feedback on those features that are effective in mitigating risks against the emerging threats.
At Tally, our Information Security Team completes a comprehensive VAPT by employing up-to-date tools and sophisticated methods, thanks to our vast experience in cyber security. Our exam-oriented approach checks every vulnerability, threat, risk, hotspot, issue, and process to test them and provide a detailed exploitation report. Our VAPT process includes two essential phases: vulnerability assessment and penetration testing.
During the vulnerability assessment phase, we critically examine the target environment for weaknesses, for instance missing configurations, obsolete applications and programs, inadequate and easily guessable passwords, unpatched computers among others. The penetration testing phase then actually recreates the hackers and tries to exploit the aforementioned vulnerabilities and to test the efficacy of existing security measures. Tests are conducted from inside Tally’s internal network and from external networks to provide an overall and realistic assessment of threats. This strategy of dual perspective gives a fairly grounded picture of our security scenario. We have Information Security to mitigate risks and ensure that any vulnerability discovered is addressed to minimise the possibility of exploitation. This way, I safeguard Tally and its subsidiaries’ online resources, uphold the best practices of cybersecurity, and guarantee the reliability and relevance of the organisational structures that support our work.
