"The Nemesis platform is designed to give security teams what they rarely get: proof that their defenses actually work. Nemesis runs safe, real-world attack simulations in your IT environment to uncover blind spots, validate your defenses, and give you the evidence you need to reduce risk and spend smarter."

Nullcon - Antriksh
"As the founder of the Nullcon security conference, I've had the pleasure of closely collaborating with the team of Peristent Security Industries. Their professionalism, expertise, and commitment to research and training have greatly impressed me. I confidently recommend their Nemesis BAS product and services based on our collaboration."
Taurus SA
SBL - Stef
"Continuous monitoring has always been at the core of what we do at SBL [...]. Adding BAS felt like a natural next step, because the two are genuinely complementary. I'd looked and tried Picus for that, but the pricing was too unpredictable to build a clean offer around. With Nemesis I know exactly what I'm paying. My approach now is to run a one-off test first, let the results speak for themselves, and the step to continuous testing is an easy conversation from there. Six months in, it's already converting well."
Taurus SA
Malware Bytes - Jérôme
"We find Nemesis BAS to be a very helpful tool to provide vulnerability exposure visibility of an environment in a quick and easy way through atomics and a nice UI. It allows to save a lot of time and efforts before scaling up security resources precisely where needed.
The entire team behind the product is great to work with!"
Taurus SA
Taurus - Jean-Philippe
"You'll never be 100% immune to phishing but PSI will show to your team how professional advanced attacks work and that's the first step to develop better detection and prevention capabilities. Red team attack simulation is one of the most effective risk reduction measures, and I can't but recommend Persistent Security!"
Taurus SA
EPI - Fritjhof
"Simply deploying more security tools isn’t enough. Instead, the effectiveness of security controls must be tested, validated, and continuously improved. Breach and Attack Simulation helps us to move from assumptions to evidence-based confidence in their detection and response capabilities."
Taurus SA
Techlab - Ethan
"Partnering with Persistent Security transformed the way we run cyberdrills. We can offer higher efficiency, lower costs and greater accuracy by running attack simulations in an automated way. Being able to offer this on a continuous basis strengthens our offering, but foremost the security posture of our clients."
Taurus SA
Best secret - Marian
"Working with Persistent Security Industries was a real eye-opener for our security team. They brought genuinely creative attacks that pushed us to think differently. The whole exercise turned into an incredible training opportunity for our SOC team, who got to defend against techniques we'd only read about in threat reports. We proved where our defenses excel and where there's room for improvement."

The Nemesis Methodology
Most organizations are flying blind when it comes to their actual security posture. Penetration tests provide snapshots, vulnerability scans miss critical gaps, and expensive security tools sit misconfigured.
Simulate
Simulate real-world cyber threats in a controlled environment. Test your existing defenses and identify gaps in your security posture.
Automate
Automate your simulation schedule by using the Nemesis scheduler and
track progressions by comparing different simulations.
Validate
Assess if your current security controls are effectively addressing, reducing, and mitigating potential threats and vulnerabilities.
Breach And Attack Simulation Technology
Atomics
Atomics are fundamental cyberattack techniques based on the MITRE ATT&CK framework, representing the TTPs used in breaches.
Scenarios
Scenarios combine multiple atomics to simulate attacks. Nemesis offers predefined scenarios and lets you create your own.
Assessments
The assessment can be seen as the final step in the process and entails the dynamic execution of your selected scenarios on a chosen agent within your environment.
