Vulnerability Assessment services are a series of tests performed on a system to identify the vulnerability of the system. This is a Security Assessment conducted to understand the vulnerabilities and by this process the vulnerabilities are identified and exposed to the security experts who in turn are able to quantify and prioritise such vulnerabilities.
Basically a vulnerability of any system refers to the inability of the system to withstand a hostile threat to its environment and the effects that may be caused by this hostile attack.
The above audits can be clubbed together in a single package as Technology Audit or can be individually done and taken up in a phased manner as per the business requirement.
The capstone of Technology Audit is the Audit Findings Report which includes gap analysis, recommendations pertaining to technology upgrade / downgrade, training requirements and plan of action.

Penetration Tests are different from vulnerability assessment services, in that they simulate an actual attack on a computer system or network as it would have been from an external or internal threat. By this method, we are able to evaluate the computer or network's security levels based on the defined objective of the test. Thus a vulnerability penetration test can help determine whether a system is vulnerable to attack, if the defence measures were sufficient and which defence methodologies (if any) were defeated in the penetration test.
As new technologies emerge and change the IT scenarios, companies have got to deal with newer audit security challenges. Thus businesses that do transactions over the internet are at high risk, though other companies are also at risk when being exposed to external networks. Thus many unforeseen traps with multiple vulnerabilities and numerous threats do manifest themselves in the least expected time and at the least expected place. Thus in order to take-up such challenges and address them, a robust system with appropriate security policies, adequate controls, periodic review and monitoring are to be in place to protect the organisation's information assets. Hence it is highly recommended to carry out an in-depth Network Assessment comprising of VA-PT audits in a periodic manner to ensure software compliance to controls established and the policies set in the organisation and further to evaluate whether they are adequate to address all the threats.
