Web Application Penetration Testing

Needsec leads the industry in web application penetration testing, identifying vulnerabilities in a range of programming languages and environments.

Infrastructure Assessments

Needsec's approach to network pentesting goes above and beyond standard vulnerability analysis.  With decades of combined security experience, our assessment team identifies, exploits, and documents even the most subtle of network vulnerabilities.  When you’re concerned about your network security, you want the top pentesting company to review it.

Red Team Assessments

Red Team Engagements are an effective demonstration of tangible risk posed by an APT (Advanced Persistent Threat). The assessors are instructed to compromise predetermined assets, or “flags,” using means that a malicious actor might utilize in a legitimate attack. These comprehensive, complex security assessments are best suited for companies looking to improve a maturing security organization.

Mobile Application Penetration Testing

Both business and public organizations today are using mobile apps in new and compelling ways, from banking applications to healthcare platforms. Managing security risk is a growing challenge on these platforms, with new vulnerabilities found every day. Is your mobile app safe from attackers?

Cloud Configuration Reviews

Penetration testing in the Azure cloud has important differences from an on-prem assessment.  This range of unique technologies often leads to complications in security architecture and configuration– as well as the penetration testing process itself.

Simulated Phishing Attacks

A phishing assessment attempts to gain sensitive information or access from a target user through coercive emails. This method of engagement is particularly effective, as attackers can often leverage public information to craft compelling emails while impersonating someone trustworthy—perhaps even individuals within the target organization.
