We bring the best talent and security “know how” to safeguard information resources from vulnerabilities and exploits.

Simple solutions are deployed across multiple platforms to enable vulnerability identification and complete system coverage and cyber protection.

Who We Are

SEMAIS provides a comprehensive view of cybersecurity, assisting clients in navigating security programs and leveraging advanced technologies. Cyber risks span multiple layers and can lead to substantial disruptions if overlooked. Organizations impacted by these threats need diverse technologies and a structured strategy to pinpoint “threat holes,” vulnerable end-points, and mitigate risks effectively. SEMAIS’s proficiency and security engagements serve as a valuable resource, offering a blueprint to tackle technology challenges and enhance risk management.


The enablement of security platforms requires a mission objective that adheres to innovation. We “do just that” – engineer innovation that aligns with the enterprise’s mission goals. Our confidentiality approach, system availability standards, and sustaining data integrity produce a cybersecurity mission objective – create a “360-Degree” security visibility program.” The end state optimizes cybersecurity initiatives and defends against cyberattacks using federal, industry, and tailored standards.


Our vision is simple: Become a steward and leader for the Cyber Workforce and build robustness that matures cybersecurity programs. We cannot do this alone – so our vision is to reimage cybersecurity into a functional strategy that articulates protection and risk reduction. Our clients’ current security state is continually assessed and navigated for improvements. We use our business strength and security knowledge to become a strategic partner – so our cybersecurity roadmaps can provide a vision that advances, monitor, and reduce ongoing risks.
