Attic Bouncer vs Silverfort Authentication Firewall: Side-by-Side Comparison (2026)

Attic Bouncer

Startup and SMB security teams that lack dedicated phishing infrastructure will find Attic Bouncer's real-time interception of fake Microsoft 365 login pages worth the browser plugin friction. The tool covers three NIST CSF 2.0 functions,identity management, continuous monitoring, and user awareness,and catches the redirect attacks and credential theft attempts that traditional email filters routinely miss. Skip this if your organization has already standardized on advanced authentication like passwordless sign-in or conditional access policies that block anomalous logins at the platform level; Attic Bouncer is a band-aid for missing MFA enforcement, not a replacement for it.

Silverfort Authentication Firewall

Mid-market and enterprise security teams will get the most from Silverfort Authentication Firewall if lateral movement is your primary concern and you need to enforce it without agents or proxies. The agentless deployment model addresses a real pain point: you can segment identity-based access and block NTLM/Kerberos abuse at protocol level without touching endpoints or requiring network appliances. Skip this if your organization lacks mature Active Directory hygiene or runs primarily cloud-native workloads where on-premises authentication controls have limited reach; Silverfort's strength lies in hybrid environments where traditional identity infrastructure is still the security perimeter.
