Vulnerability assessment is the process of identifying, classifying and prioritizing weaknesses in the assets in scope. These assets could be infrastructure, applications and/or devices. Defendza offers this exercise with a hint of human intelligence added to remove false positives. However, this is not a concentrated manual effort as demonstrated via penetration testing. 

Don't make a mistake of buying a vulnerability scan disguised as a vulnerability assessment. The goal of the vulnerability assessment is to scan and provide a list of vulnerabilities affecting your network, and explain the attack impacts and likelihood of exploitation. 

Get in touch to discuss this in-depth with one of our security experts.

Why you need Vulnerability Assessments?

Security researchers such as freelancers, bug bounty companies are finding bugs regularly. Regular vulnerability assessments are one of the important ways to identify and quantify the potential risks threatining your environment.

Manual penetration tests are not only time consuming, but also cost intensive as they are focussed and include exploitation of vulnerabilities. Vulnerability assessments are a useful way to assess larger networks regularly in shorter time periods and are a useful way to prepare for penetration testing.

Communication & Debrief

We take customer communication as seriously as reporting or assessment execution. We engage with customers during all stages, and ensure that customer contacts are up to date in the language they understand. Post engagement, a free debrief is conducted to help the customers understand the weaknesses and prepare a mitigation plan.


The assessment-execution phase is followed by the analysis & reporting. Defendza performs analysis on the testing output, evaluates the risk impact and likelihood of exploitation in realistic scenarios before providing action plans to remediate the identified risks. All our reports address business as well as the technical audience with supporting raw data, including mitigation measures at strategic and tactical levels. 

Vulnerability Analysis

The prioritised list of targets is scanned for vulnerabilities. This assessment involves checking both published as well as undocumented vulnerabilities against the target assets.  We sift through the scan results for false positives. The manual assessment ensures that only verified vulnerabilities are focused upon.

Vulnerability Scanning

This phase includes running vulnerability scanner excluding any dangerous plugins to find weaknesses in the scoped systems. This exercise is scheduled in automated fashion unless explicitly agreed to limited timescales with a customer. 


In this phase, we profile the target, i.e. a network, a server, or a device. This is a non-intrusive exercise and involves activities like analysing the network, understanding the different assets and services, operating systems, programs in use, and anything related to network layout. This is a fundamental step and helps to prepare for the next stage of finalising targets and finding weaknesses.

"My experience to date with Defendza has been very positive, I look for a flexible, knowledable security "partner" when I engage a PT firm. Pentest means many things to many people and there are many different use cases for both the testing activity and the report generated and I need someone to work with me to get the absolute best value out of my security budget."
