External Penetration Testing

Attackers have many tricks to gain access to your data and network. Will your perimeter stand up to breach attempts from an external vantage point? External penetration testing explores what damage a malicious hacker could achieve without privileged access.

It is a comprehensive test that models the more common opportunistic type threat actor. Our security engineers attempt to collect sensitive information through open-source intelligence to gain internal network access. The engineer also performs scanning and enumeration to identify vulnerabilities that can be exploited.

The NESTT Approach

Testing Methodology

Our security engineers base testing on the NIST SP 800-115 Technical Guide to Information Security Testing and Assessment, OWASP Testing Guide v.4, and customized testing frameworks.

Our Tactical and Strategic Recommendations Enhance Your Security Posture

After your engagement with us, you can use your NESST Security Assessment Findings Report to prioritize, manage, and remediate each threat, saving you time and resources. Our comprehensive Findings Reports contain detailed remediation advice and guidance.

Modern pentests to fight modern hackers.

  • Planning: Scope is defined and rules of engagement are set.
  • Intelligence Gathering: Reconnaissance is performed to gather information on the target systems. This information determines what types of attack vectors the pen test will use.
  • Threat Modeling: Potential threats are enumerated and prioritized. Everything from a hacker’s point of view. This stage provides a systematic analysis of the probable attacker’s profile, the most likely areas of attack, and the assets that are most desired by an attacker.
  • Vulnerability Analysis: Security flaws in the target systems are uncovered using active scans and manual techniques.
  • Exploitation: This is where the vulnerabilities that have been discovered are exploited in order to gain access. This stage is where the NESTT insight and ingenuity comes to play.
  • Post-exploitation: Compromised targets are further assessed to determine the value of the machine and to maintain control of it for later use.
  • Reporting: Good reporting is key to obtaining value from a penetration test engagement. NESTT documents all found vulnerabilities and exploits, failed attempts, and company strengths and weaknesses. We also include crucial remediation recommendations.
  • Problem Solving, Productivity, And Value
