Who We Are

Want to be part of a company that empowers you to innovate and implement your powerful ideas as you help shape the future of cybersecurity? Since 2012, CRITICALSTART has assisted in safeguarding numerous businesses from cyberattacks, preparing them for upcoming threats, and earning a plethora of awards along the way. 


We thrive on innovation, devoid of bureaucracy. CRITICALSTART pioneered the first MOBILESOC app for on-the-go threat detection and response, devised a method to automatically resolve the majority of security alerts, and introduced services that reduce alert investigation time by 99.3% (our analysts truly appreciate us for that). 


Everything we do revolves around our three core principles: 


Do what’s best for our customers.  

Do what’s best for our employees. 

Don’t do things that suck. 


That's basically it.

  • An approach of continuous improvement to revolutionize our industry and surpass mediocrity. While many cybersecurity companies hire competent individuals, we believe in striving for excellence. Don't you believe you're capable of more than just being good? 
  • Constant learning, unlocking innovative ideas, and a nurturing, cooperative environment. 
  • Extensive industry recognition. We receive so much acclaim that it's nearly overwhelming. Almost. 
  • Our teammate put it best: "Every day presents new challenges and ample opportunities for professional growth... Your contributions directly impact the company's overarching purpose, and the sense of belonging and culture are unparalleled.
