Attack Simulation

Learn your weaknesses before the adversary does.


This is the Nisos Advantage.

Our operators are hand-picked experts, each with in-depth experience in offensive cyber operations.

Our teams have been the adversary before giving them direct relatable experience. Our operators use this hard-won knowledge, along with tools favored by threat actors, to simulate the full breadth of sophisticated attack.

Nisos attack simulation is the ultimate tool your organization can use to raise security posture and improve response time to real threats.

Our Expertise Makes the Difference

Nisos has one of the highest concentrations of former U.S. Government offensive operators, each of whom have deep experience as de facto nation-state threats. We operate with a level of creativity unmatched in the private sector, calling on deep knowledge of various environments and techniques to ensure the results and analysis you receive are comprehensive and impactful.

We increase the value of our findings and recommendations by ensuring the output is digestible by business leadership. Our reporting translates the technical aspects of the simulation to the practical impacts to corporate value.

Penetration Testing

True pen testing requires people with advanced skill sets and experience to effectively compromise your digital infrastructure. Our operators go in blind and take down the most secure networks to giving you the most holistic understanding of your gaps and vulnerabilities.

Red Team

Our Red Teams take on your organization holistically from top to bottom. The team you turn to when you absolutely, positively need to know where your defenses are vulnerable. Nisos operators bring real-world attack experience to your organization that no one else in the industry can offer.

Purple Team

We work collaboratively with your blue team to simulate adversarial activity on your network, measure your ability to detect, respond to and mitigate the malicious activity and identify gaps that leave you vulnerable to attack — all in real-time.

Physical Security Assessments

We assess your security hardware and access control systems, as well as put your personnel and procedures to the test to better illustrate where you’re vulnerable and how best to mitigate the threats.

Social Engineering

We show you how attackers can compromise your security and steal essential data through careful and thorough reconnaissance of your digital footprint and the social media activity of your employees and leaders.

App & Cloud Security

Your attack surface is so much more than just your network hardware. Nisos’ operators will evaluate your existing application stacks and cloud assets to ensure your assets are safe from attackers.
