OnSystem Logic is a fast-growing security software start-up in the greater Washington, DC metropolitan area. We developed OnSystem Defender, the first and only non-bypassable application security product on the market.
Our Focus is Application Security
Our unique approach, technology and product, OnSystem Defender, offers companies the best available protection against harmful malware and application flaws. The last frontier in malware protection is the application, which is where ALL current endpoint security products are routinely turned off or otherwise bypassed by attackers. Our patent pending In-Memory Application Reference Monitor is non-bypassable. An attacker cannot violate our rules in ANY way.
Why We Started the Company
- Deep conviction that security is of the utmost importance for any company’s success in this digital age.
- Current Anti Virus products are completely inadequate at protecting applications from sophisticated malware attacks. They are reactive and assume attackers don’t know what the protector is doing.
- Companies are typically severely delayed in patching their environments of known vulnerabilities.
- Zero Day attacks expose every company to constantly changing malware threats.
- A different approach was needed to address all these existing and growing exposures.
- We possessed strong domain expertise in secure operating system design and sound computer security. We started working on solving these problems in 2015.
- Wanted to build another high-integrity, high-performing, collaborative culture and successful company.
