What Excalibur does

Excalibur s.r.o. is a Slovak-headquartered (Poprad, Slovakia) cybersecurity software vendor that builds Excalibur SAM (Streamed Access Management), a next-generation privileged access management platform replacing legacy PAM, VPN, VDI/Citrix, WAF, and endpoint security tools with a single zero-trust, isolation-centric system. Its core proprietary technology, called VITRO, streams only sanitized pixel-level visual and interactive instructions to the end-user device, creating a virtual air gap between the endpoint and sensitive target systems and supporting web, RDP, SSH, and VNC protocols. The platform adds passwordless MFA with biometric and hardware-key options, full video-fidelity session recording, and AI-powered real-time intent analysis with anomaly-triggered session pausing, dual-control approval, and RLHF continuous learning.

The company monetizes through two deployment models: a SaaS subscription (annual, fully managed Kubernetes in EU data centres) and an on-premises / private cloud perpetual license (multi-year contracts, including air-gapped and government/defence-ready deployments). Pricing is quote-based and not publicly disclosed. Go-to-market is 100% channel-first, relying on dedicated programs for MSPs, SOCs, System Integrators, and Distributors, supplemented by direct enterprise field sales for SaaS and on-premises engagements. Target customers are mid-market and enterprise organizations in the EU's 18 NIS2-regulated critical sectors — energy, banking, health, public administration, and digital infrastructure — where EU data sovereignty, CLOUD Act immunity, and NIS2/GDPR audit-ready evidence trails are procurement requirements. The platform is ISO 27001/27017/27018 certified and built around a Kubernetes-native cloud architecture, with R&D activity located in Bratislava and product development partially co-funded by the European Cybersecurity Competence Centre (ECCC) and the Slovak Republic's Recovery and Resilience Plan.

Direct peers

• CyberArk: CyberArk is the global leader in Privileged Access Management, offering session management, credential vaulting, and just-in-time access for enterprises. It is the most direct competitor to Excalibur SAM in the PAM space, and the reference vendor Excalibur positions against in its 'legacy PAM vs. Excalibur' comparison.
• BeyondTrust: BeyondTrust provides unified Privileged Access Management with privileged session management, endpoint privilege management, and remote support. It competes head-to-head with Excalibur in mid-market and enterprise PAM deals across the EU.
• Delinea: Delinea (formerly Thycotic + Centrify) is a major PAM vendor offering privileged credential management and session recording. It targets the same enterprise/government buyer segments as Excalibur and is a primary displacement target in regulated EU verticals.
• Teleport: Teleport is an identity-native access platform combining zero-trust SSH/RDP/Kubernetes access, MFA, and session recording. Its 'access plane' architecture and engineering-centric buyer base make it the closest modern architectural peer to Excalibur SAM in the EU mid-market.
• StrongDM: StrongDM provides a unified access plane for databases, servers, Kubernetes, and web apps with just-in-time credentials and session auditing. It targets the same modern infrastructure access use case as Excalibur and competes for similar DevOps and platform engineering buyers.
• Island: Island pioneered the Enterprise Browser category, providing browser-level isolation, DLP, and governance for SaaS and internal web apps. Its browser-isolation-led approach to enterprise access and web application security closely mirrors Excalibur's VITRO/RBI WAF architecture.

Emerging players

• HashiCorp Boundary: HashiCorp Boundary provides identity-based session access to infrastructure without exposing credentials, with session-level auditing. It targets a similar developer-centric, infrastructure-access use case as Excalibur but is positioned as an emerging, infrastructure-tooling alternative rather than full enterprise PAM.

Broad incumbents

• Microsoft Entra ID: Microsoft Entra ID (formerly Azure AD) is a broad identity and access management platform with Privileged Identity Management (PIM) capabilities. It is bundled into Microsoft enterprise agreements and represents the default incumbent that Excalibur must displace to win large enterprise and public-sector accounts.
• Zscaler Private Access: Zscaler Private Access (ZPA) is a cloud-native ZTNA service replacing traditional VPNs for application access. As a broader zero-trust network access platform, it overlaps with Excalibur's VPN-replacement positioning for enterprise network access use cases.
• Cloudflare Access: Cloudflare Access is a Zero Trust Network Access (ZTNA) product within Cloudflare's broader security platform, including WAF capabilities that overlap with Excalibur's RBI WAF. As a global infrastructure incumbent with bundled pricing, Cloudflare is a frequent competitor in EU enterprise security procurements.
