Head to head · 2026

Silverfort sells you a platform.
Authnull closes the gap by Friday.

Same gap, two very different purchases - one is an enterprise programme, the other is a line item you switch on. Here is the whole comparison in one frame.

Not in their product

Every database connection challenged and logged - not just the domain login.

Auditors ask who touched production data, and an identity-protocol tool cannot answer that. Authnull sits in front of MySQL and PostgreSQL as a proxy: a factor on connect, live masking on sensitive columns, and a full query trail - inside the same flat price as your AD enforcement.

Silverfort
Database connection MFA and masking are outside the offering - this gap stays open after the platform purchase.
Authnull
Included in the base price, same policy engine and same console as AD, RADIUS, and Linux.
Authnull vs Silverfort · full comparison

A complete, dimension-by-dimension comparison.

A capability-by-capability breakdown across architecture, coverage, product category, and positioning - fourteen dimensions in total, including where Silverfort leads.

Core architecture
3 of 3
Approach
architecture model
Agent/proxy-based
Agent/proxy-based unified identity protection layer sitting in the auth path.
Credential-free
Agentless, credential-free MFA and Zero Trust access - no standing credentials to vault or steal.
Deployment

Console + connectors
Console plus connectors/proxies - marketed as agentless on the endpoint, but infrastructure components sit in the identity flow.
No endpoint agents
No agents on endpoints; integrates at the protocol/directory level.
Credential handling

Extends existing creds
Extends MFA and policy enforcement around existing credentials rather than removing them.
Eliminates credentials
Eliminates persistent credentials - session-based, credential-free access.

Core pitch
the one-line pitch
Extend MFA to legacy systems
“Add MFA and risk-based policy to systems that can't natively support it.”
Remove the credential
“Remove the credential entirely.”

ideal buyer
Blanket legacy/hybrid visibility
Orgs wanting to blanket legacy/hybrid environments with MFA and identity risk visibility without touching endpoints.
Eliminate standing credentials
Orgs wanting to eliminate standing credentials across legacy on-prem infrastructure.

Authnull leads on 11 of 14 dimensions and ties on 1. The remaining 2 - cloud/SaaS breadth and ITDR - are areas where Silverfort leads.

Get this as a scorecard
The platform tax

The gap costs the same to close either way. The buying doesn't.

A platform purchase carries everything around the product: the cycle, the quote, the rollout, the training, the owners. None of that makes the auditor's finding go away faster. Here's what you skip.

Compare the real cost
skipThe 6-week enterprise sales cycle
skipA quote you can't benchmark against anything
skipAn annual commitment before the first policy runs
skipA rollout project with a name and a steering call
skipPaying platform rates for modules you'll never open
How teams switch

Prove it on the finding. Keep what works. Drop the platform bill if you want to.

01 / this week
Close the finding

Point Authnull at the exact paths the auditor flagged - AD logon, RADIUS, RDP, databases. Free tier, no procurement.

02 / next month
Take the enforcement load

Move the enforcement paths onto flat pricing and shrink the platform to what only it can do. No rip-and-replace.

03 / at renewal
Decide with numbers

If Authnull covered the gap, renewal is an easy conversation. If you truly need ITDR depth, keep it - we'll tell you straight.

You can read our price, start free, and be enforcing MFA before a platform demo gets scheduled.

Twenty minutes on your real environment. We'll show you which flagged paths we close today - and be honest about the ones we don't.
