Firewalls and endpoint detection solutions have their place, but they struggle to cope with increasingly sophisticated attacks such as ransomware and long cycle attacks. ActZero inspects every layer of your environment. Our cybersecurity professionals are poised to act 24/7, and communicate with you as an extension of your team.


Combine full threat landscape coverage, EDR visibility and machine learning, and you get automated identification of previously unknown threats. ActZero sees what others miss, with comprehensive detection across endpoints, networks and cloud environments.


Advanced, real-time remediation is where ActZero really stands out—in uptime, safety, customer experience, data protection, and brand equity. ActZero's threat hunters think automation first, executing tailored plans to stop your threats and mature your security posture.

Cost-Effectively Execute and Scale Cybersecurity

Assembling your own detection and response capabilities from scratch is expensive and time-consuming even if you have (or think you can get) the right personnel to build an effective SOC. ActZero's platform and skills make the business case for our partnership obvious. We instantly make your team more effective and reduce your risk. Compliance is as easy as closing the security gaps we identify. Your security posture improves progressively, and you stay ahead of threats, compounding the value of your MDR investment.


“Other companies try to replicate what ActZero, and they can’t deliver it in the same way. ActZero has a better tool stack, better people at a commodity price that allows us to blend it into our service offering to deliver with true confidence and at a price that is highly affordable. We can deliver an affordable enterprise-grade service to a 25 or 50 person company.”

Jayson Kiel, President & CEO, Lockmann Krane
