Silverfort Alternative: Compare Silverfort and 8Layers

Verdict

Their clearest documented distinction is architectural emphasis. Silverfort markets inline runtime protection, Universal MFA, and an Authentication Firewall. 8Layers documents historical signal correlation, investigation timelines, causality graphs, and identity-control evidence.

8Layers response actions should not be described as equivalent to Silverfort's inline authentication enforcement.

Verified comparison

Area	8Layers	Silverfort
Positioning	Unified identity security platform: posture, detection, and compliance	Runtime identity security
Primary orientation	Cloud-first, identity-data layer with unbounded history	On-prem/hybrid-first, inline enforcement with deep AD/legacy coverage
ITDR	Real-time detection and post-authentication correlation: catches anomalies as they happen and reconstructs multi-stage kill chains across the full identity history, including threats that only reveal themselves after access was granted	Real-time detection inline in the authentication flow: evaluates protocol, behavior, and threat-pattern signals at the point of access to allow or block before authentication completes
ISPM	Assigns one compound risk score per identity across every IdP and federation trust chain in cloud and hybrid environments, with formal, auto-expiring risk waivers	Discovers misconfigurations, legacy-protocol exposures, and shadow admins across hybrid and AD environments, scoring by probability and business impact
Response model	Agentless, API-based response on detection (block, kill sessions, revoke tokens)	Inline enforcement in the authentication path (block, MFA challenge, session termination)
Deployment	100% SaaS, agentless with no changes to the authentication flow	Inline in the authentication path (proxy/enforcement point)
Detection transparency	Detections mapped to MITRE ATT&CK, written in a readable, auditable language, and extensible by the customer (no dependence on vendor rule libraries)	Multi-layer detection (protocol, behavior, threat patterns) with vendor-provided playbooks and recommendations
NHI and AI agents	Treated as first-class identities in one unified model, receiving the same handling as human identities	Covered via dedicated modules (Non-Human Identity Security, AI Agent Security)
Investigation	Self-contained investigation workspace (visual timeline, causality graph, related entities, with response in the same screen)	Enriches alerts with forensic identity context and forwards them to external SIEM, XDR, or SOAR
Compliance	Dedicated module with continuous validation, drift detection, and audit-ready evidence	Compliance achieved by enforcing the controls regulations require across regulatory frameworks
Pricing	No numeric prices found	Packages, but no list prices

What 8Layers publicly documents

8Layers connects Thor for ITDR, Octagon for ISPM, and Compass for identity-control compliance through a shared identity-data layer.

Documented response actions include block, session termination, token revocation, and credential scrambling. Specific actions available depend on the connected system and should be confirmed per integration.

What Silverfort publicly documents

Silverfort positions itself around runtime identity security. Its public pages describe inline protection, Universal MFA for legacy and custom systems, an Authentication Firewall, ITDR, ISPM, NHI security, and AI-agent security.

It also describes coverage spanning on-premises, OT, hybrid, cloud, and multicloud environments. Documented response actions include denial, MFA challenge, session termination, virtual fencing, and access quarantine.

Documented strengths and review limitations

8Layers

Documented strengths: Detection across the full attack lifecycle (persistence, privilege escalation, and lateral movement after login, not just at authentication) correlated across the full identity history, with investigation timelines, causality graphs, response actions, and compliance evidence.

Review limitations: Response is agentless and API-based rather than inline; enforcement on legacy or non-cloud systems should be validated. Actions may vary by integration.

Silverfort

Documented strengths: Inline runtime protection, Universal MFA, Authentication Firewall controls, and coverage for hybrid and legacy systems.

Review limitations: Protection sits inline in the authentication path, a model to weigh against agentless approaches. List pricing is not public and module availability can depend on environment.

Which product should you evaluate?

Consider 8Layers when you specifically need:

ITDR and ISPM sharing an identity-data layer.
Historical kill-chain correlation, timelines, and causality graphs.
Continuous identity-control evidence for ENS, NIS2, ISO 27001, or SOC 2.

Consider Silverfort when you specifically need:

Inline runtime access protection.
Universal MFA for legacy, custom, command-line, or OT access.
Authentication Firewall controls across hybrid infrastructure.

These criteria reflect public documentation, not independent testing.

Pricing

Silverfort publishes Core, Plus, Advanced, and Enterprise packages. It says pricing depends on organization size, but does not publish numeric list prices. Buyers must request a personalized quote.

No numeric 8Layers pricing was found on the reviewed public pages.

Methodology and limitations

We reviewed current first-party platform, product, compliance, and pricing pages on 13 August 2026. We did not test deployment, response coverage, or performance.

Confirm module availability, integration-specific actions, and final pricing with each vendor.

Star ratings and review counts are not included because this review did not verify a consistent, current third-party dataset for both vendors.

FAQs

The reviewed 8Layers pages document response and containment actions. They do not establish Silverfort-style inline authentication enforcement.

Yes. Both vendors label ITDR and ISPM capabilities. Their detection methods, deployment architecture, and response coverage should be tested.

Silverfort publishes four package levels and a size-based pricing model, but not numeric list prices.
