Versa UEBA incorporates GraphML to generate insights and detect anomalies in user relationship graphs. Anomaly and behavior detections are just the first step. We then need to quickly pivot into building the forensics to inform response and remediation. This can involve determining the origination point of a malicious activity or an attack and building the scope and scale of a potential breach.

Introduction: Interest in SASE has exploded with CIOs and CISOs alike. The promise of dramatic cost reductions, security improvements and improved agility delivered by a converged networking (SD-WAN) and security (SSE) infrastructure is compelling. However, today’s SASE solutions are commonly delivered on a shared global infrastructure of PoPs provisioned by a handful of technology vendors. This approach doesn’t always meet everyone’s requirements. A “shared” SASE approach is generally good enough for many companies, delivering unified networking and security capabilities with fast time to market and cloud/SaaS economics. But because these shared services lack any ability to control and manage service…
