What they do

A Vulnerability Analyst or Penetration Tester probes for and exploits security vulnerabilities in web-based applications, networks and systems. Penetration Tests are designed to achieve a specific, attacker-simulated goal and should be requested by customers who are already at their desired security posture. A typical goal could be to access the contents of the prized customer database on the internal network, or to modify a record in an HR system. Vulnerability Assessments are designed to yield a prioritized list of vulnerabilities and are generally for clients who already understand they are not where they want to be in terms of security. The customer already knows they have issues and simply need help identifying and prioritizing them.
