Elisity

We’re honored that Elisity was named in the Gartner® Cool Vendors™ in Cyber-Physical Systems Security 2025 report. In our opinion, protecting thousands of connected devices demands more than visibility. It requires identity-based microsegmentation that enforces least-privilege access for every user, workload, and device — without disrupting operations. We believe Elisity’s platform transforms existing network infrastructure into intelligent policy enforcement nodes, helping organizations accelerate Zero Trust maturity in weeks, not years.

Great breakdown from Peter Welcher on why the how of microsegmentation matters as much as the what. His point about tag-based enforcement turning switches into a "distributed firewall" vs. the months of VLAN planning and IP changes with legacy NAC? That's exactly why our customers tell us they can implement in weeks instead of years—using infrastructure they already own. Worth the read for anyone evaluating network security approaches: https://lnkd.in/en33ZvUW #Microsegmentation #ZeroTrust #NetworkSecurity #IdentityBasedSecurity #LateralMovement #NAC

If your NAC project has stalled, you're not alone. NAC projects don't fail because of your team. They fail because of the technology itself. Here's what security leaders are discovering: The complexity isn't a skills problem. It's an architecture problem. 802.1X dependencies, certificate management nightmares, IoT devices that can't authenticate, and VLAN sprawl that becomes unmanageable at scale. The result? NAC typically covers only about 33% of devices on modern networks. The other 67%—IoT sensors, medical devices, industrial controllers—remain outside its reach. The good news: Modern identity-based microsegmentation and ZTNA are delivering the security outcomes NAC promised, without the complexity. Our latest blog breaks down: → Why NAC struggles with IoT/OT environments → The technical realities behind stalled deployments → How hybrid approaches are working today → A pragmatic path forward for security teams Link in first comment 👇 #ZeroTrust #Microsegmentation #NetworkSecurity #CyberSecurity

Security architectures that worked in 2024 won't cut it in 2026. Our CTO Piotr Kupisiewicz shares six shifts that will separate solutions that scale from ones that get replaced after two years. Here's what security engineering leaders are planning for: 👉 Single-tenant control over shared infrastructure Customers want their data isolated—not labeled in a shared database with hundreds of other companies. 👉 Policy simulation before production Shipping security policies straight to production without testing? That's how you block the CFO from the ERP system at 2pm. 👉 APIs that share context, not just alerts EDR detects behavior. SIEM correlates. Network segmentation isolates—automatically. One-way data flows are legacy thinking. 👉 Enforcement at the edge Centralized policy decisions with distributed enforcement. When cloud connectivity drops, security fails closed, not open. 👉 Data quality as the foundation Garbage identity data produces garbage policies. Solutions that reconcile AD, CMDB, and network telemetry into one source of truth win. 👉 Real-time correlation at scale Cloud-native architectures now make it possible to correlate millions of events per hour and adapt policies based on live state changes. The article breaks down practical approaches for each shift.

Healthcare security teams face an impossible equation. 884 incidents affecting healthcare providers since January 2023. 72% of organizations that experienced cyberattacks suffered disruption to patient care. Yet traditional security approaches remain too complex, expensive, or disruptive for environments where patient care cannot stop. Our CTO Piotr Kupisiewicz explores how identity-based microsegmentation is breaking through this paralysis in his latest article for Health IT Answers. Key insights for healthcare security leaders: → Why traditional network segmentation requires multi-year implementations costing tens of millions → How one healthcare system reduced forecasted spend from $38M to $9M (76% reduction) while implementing in weeks instead of years → The practical path to Zero Trust that works with existing infrastructure—no new hardware, agents, or disruptive network changes required → Why organizations using NIST's Cybersecurity Framework report one-third lower cyber insurance premium growth The question isn't whether to implement Zero Trust. It's which approach delivers effective security within real-world operational and financial constraints.

We are proud to announce: Elisity ranked #13 on the 2025 Deloitte Technology Fast 500™ We achieved 8,860% revenue growth over three years by helping enterprises solve a critical challenge: implementing network segmentation in weeks, not years. Why this matters for security leaders: Traditional microsegmentation projects often become multi-year initiatives requiring new hardware, agents, and complex VLAN configurations. Our customers are proving there's a better way. The shift to Zero Trust is accelerating. Organizations are moving beyond legacy NAC and perimeter-based security to identity-based microsegmentation that actually gets deployed. What's driving this growth: → Enterprises need microsegmentation that works with existing switching infrastructure → Security teams want rapid deployment without network downtime → IT leaders require visibility into every device - managed and unmanaged → Organizations demand automated policies that adapt to changing risks Our Elisity IdentityGraph™ technology discovers every user, workload, and device on your network, then applies dynamic security policies wherever devices appear - all without agents, new hardware, or network redesign. This recognition reflects our customers' success in achieving Zero Trust maturity and stopping lateral movement attacks.

Day 1 at Forrester Security & Risk Summit just wrapped, and three things are crystal clear: AI agents are coming whether security teams are ready or not. Despite 60-90% failure rates, the economics are too compelling to ignore. But here's what stood out most for network security leaders: Zero Trust governance is the #1 blocker.37% of organizations say lack of alignment between IT, security, and enterprise architecture teams is delaying their Zero Trust initiatives. Not budget. Not technology. Alignment. Carlos R.'s framework broke this down into three layers that actually work—Strategic (the why), Operational (the how), and Tactical (the what gets enforced). Soo Youn Yi from PNC Bank shared their "governance factory" approach that's worth studying. The key insight? Identity-based controls are the foundation that ties it all together. Without proper governance connecting your identity, network, endpoint, and data teams, you're launching initiatives that become expensive experiments with no clear ROI. George Colony and Amy DeMartine opened with AEGIS—Forrester's framework for securing agentic AI. Allie Mellen broke down the "security singularity." Erik Nost closed with a reality check on proactive security. Jess Burn and Jeff Pollard revealed the 30% "AI tax" on security salaries coming within two years.

Sometimes the most important work we do has nothing to do with cybersecurity. Our team recently came together for something that matters deeply to us: bringing joy to kids facing medical challenges. Through our First Team fundraiser, we raised $6,902 and delivered 690 art kits to children's hospitals across the country. What started as a $5,000 goal turned into something bigger when our employees stepped up. The photos say it all – our team personally delivered these kits to 10 hospitals from coast to coast. Every kit gives a child hours of creative escape. Drawing, building, designing – simple activities that make hospital stays a little brighter. With Halloween here, we wanted to make sure kids in hospitals could enjoy the fun too. These art kits bring creativity and smiles when it matters most. Hospitals we donated to: St. Jude Children's Research Hospital Orlando Health Arnold Palmer Children's Hospital Children's Hospital of Atlanta Children's Hospital of Philadelphia Children's Hospital of Alabama Rady's Children's Hospital Stanford Medicine Children's Health Duke Children's Hospital Texas Children's Hospital Children's Mercy Kansas City This is what corporate responsibility looks like in action. Not just writing checks, but showing up. Thanks to every Elisity team member who contributed and delivered. You made this happen. #CorporateResponsibility #Healthcare #GivingBack #ChildrensHospitals #Leadership #TeamCulture #MakingADifference
