Testing for penetration
A penetration test involves simulating an actual-life cyberattack on a firm’s networks and IT infrastructure to detect possible holes and flaws.
Auditing is done physically by a security specialist who simulates activity by hackers to discover possible safety risks and evaluate the ability of the company to spot and react to attacks.
Risk Assessment
A risk assessment measures an establishment’s total safety risk outline by assessing possible threats posed by vulnerabilities and the probability of existence.
Auditing social engineering
A social engineering audit evaluates a company’s sensitivity towards social engineering assaults including phishing attacks, fraud, and trolling. The purpose is to identify weaknesses in the company’s safety education and provide recommendations for improving them.
Auditing configurations
The configuration audit examines a company’s IT settings to verify that the systems are trustworthy and meet regulatory requirements. Its main objective is to identify possible risks to safety and provide recommendations for improving the safety of the business.

Tests & Assessment
- To ascertain the efficacy of the company’s security procedures, the auditing group will thereafter carry out several procedures and evaluations.
- This could include scans of vulnerabilities, hacking exercises, methods of social engineering tests, or different kinds of privacy evaluations.
