In a perimeter-less world, identity is the foundation of your security

With the ever-expanding ecosystem of mobile workers, cloud services, and devices, identity is the only control plane left for keeping the bad guys out. At the same time, identity is the primary attack surface. Semperis enables identity-first security, starting with the core of your identity infrastructure: Active Directory on-prem and in the cloud.

Identity threat detection and response (ITDR) is a Gartner “top trend” for cybersecurity

“While organizations understand the criticality of AD, the security of AD is often overlooked. If AD is breached, an attacker gets virtually unrestrained access to the organization’s entire network and resources. This makes AD a prominent high-value target for threat actors.”

Advanced actors are attacking on-premises identity deployments to effect systemic breach and bridge to cloud admin access. Organizations in hybrid Active Directory environments need identity-first security to protect their AD and Azure AD systems from attack. This requires continuous monitoring and assessment of AD and Azure AD security posture to defend against identity-based attacks in partnership with traditional security teams.
Alex Weinert VP of Identity Security, Microsoft

Semperis has a differentiated solution that focuses on securing the databases and domain services that connect users and comprise Active Directory – and are often the primary entry points for attackers. This technology is tackling the universal challenge of identity-based attacks holistically, supported by an incident response team with enormous expertise and experience.

Working at the largest retailer in the world, I was constantly on the cusp of the digital revolution—combating the severe cyber risks it introduced, while still enabling the business to harness its transformative power. As a strategic advisor to Semperis, I’m excited to continue this mission by helping companies in the retail sector and beyond to be more cyber resilient so they can embrace the future, not fear it.

Active Directory is the ‘Achilles’ heel’ for enterprise security programs. Semperis is offering a timely solution considering that AD has been at the center of many widespread and business-crippling attacks in recent years.

Semperis is a mission-driven company uniquely positioned to not only help organizations prevent costly downtime, but also to curb the funding of evil. When organizations can say ‘no’ to blackmail and ransom demands, we’re all safer.
Ed Amoroso Founder and CEO at TAG Cyber

Enterprises too frequently underestimate the importance of Active Directory security and recovery. Enterprises are learning the hard way that if ransomware takes AD down, the entire business goes down with it. Semperis came to market with solutions and service offerings that dramatically increase the operational resiliency of organizations everywhere, starting with the core identity system, AD. I’m proud to be part of the mission and join the industry’s most skilled collection of AD security experts.
