Enterprise identity teams have invested billions in IGA, IdPs, and PAM, yet 78% of breaches still involve compromised credentials and associated standing access. Why? Because these tools manage identity in isolation, creating fragmented context and static access decisions that cant adapt to real-time threats. Meanwhile, attackers exploit the exposure windows between when access is granted and when it should be revoked. SGNL pioneered Continuous Identity—centralizing all identity and security context into a unified intelligence layer that evaluates and orchestrates access decisions at the speed of business. Our platform doesnt just monitor—it actively orchestrates access based on real-time context: business activity, security posture, behavioral patterns, and environmental factors. We integrate seamlessly with your existing IAM investments, dramatically improving their performance while eliminating the legacy bottlenecks that create risk and drive up costs. The result: access that finally matches reality, exposure windows that disappear, and an IAM program that actually works. It’s why multiple Fortune 100 companies and fast-growing, global enterprises alike are turning to SGNL to reduce their identity attack surfaces, and why SGNL is backed by top security technology investors including Cisco and Microsoft.
