Open Systems

Why Crazy Good Cybersecurity

The escalated threat level, the cyber talent shortage, and the sheer complexity of deploying and managing a multitude of security solutions, are the perfect storm for security and IT teams. We are deeply passionate about protecting organizations from that storm.

We provide a set of AI-based, cloud-delivered security solutions that are simple to deploy and manage, and provide the highest level of protection. And Mission Control, our integrated NOC and SOC, is staffed by experts, not only in threat hunting and cyber hygiene, but also in the proper configuration and maintenance of the Microsoft security stack. So we can leverage what you already own.

The combination is changing the lives of our customers, giving them security traditionally reserved for only the largest organizations. We give them “shelter from the storm”. That is our passion.

​We’re constantly refining our approach to make customers’ cloud and security systems work better together for a world always in flux. As a result, we’ve pioneered a SASE that’s adaptable and scalable. We’ve also integrated a zero-trust approach to ensure businesses have secure access, wherever their people may be. And our unique MDR service aims to minimize disruptions to customers’ operations through precision containment.

Outstanding People, Unconventional Thinking

At Open Systems we know that amazing technology is nothing without amazing people. That’s why we only hire the best engineers. Then we give them 400+ hours of additional training so that they know our Mission Control systems inside-out. This combination of top-class talent, advanced AI, and machine learning capabilities means we can offer intelligent systems that are both proactive and reactive, allowing our teams to focus in on the tough calls needed to keep our customers’ businesses running smoothly.

Open Systems has been recognized as a great place to work. It is led by a team of cybersecurity experts with outstanding backgrounds in security and networking services design. Our team has a wealth of knowledge around building and scaling successful companies and believes in a great internal culture where people feel appreciated and can continue to learn.
