Sentar is a cyber intelligence company, combining innovative technologies with world class solutions and subject matter expertise to protect our national security and way of life by innovating, building, and securing mission-critical assets.

At Sentar, we recognize that cybersecurity is essential, but not sufficient in tackling the ever-evolving cyber threat; in order to deliver effective outcomes, we must bring expertise in technical disciplines: cybersecurity, intelligence & analytics, systems & software engineering.

Our outcomes focus on resilience, predictive and proactive operations, automated incident response, risk awareness for decision-making, and deriving intelligence from large datasets. We have also established a strong history of analytics innovation, developing technology using artificial intelligence, machine learning, and agent-based algorithms long before those terms were in vogue. Underpinning our solutions and capabilities, our vision remains aligned with the evolving cyber domain, and is an inspirational mandate to keep us focused on desired outcomes.

In a connected world, cyberattacks present a threat to every aspect of our society.

Our passion is protecting our nation’s security and our way of life by innovating, building, and securing mission critical assets.
