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.

Silverfort coverage is based on its published capabilities as of October 2026. Partial means it depends on deployment or needs more platform modules.

A complete, dimension-by-dimension comparison.

A capability-by-capability breakdown across architecture, coverage, privileged access, pricing, product category, and positioning - 19 dimensions in total, including where Silverfort leads.

Capability
Silverfort
Authnull
Core architecture
Leads 2 of 3
Approach
architecture model
Identity security platform
A broad identity security platform: MFA in the auth path, ITDR, privileged access, non-human identities, posture and cloud identity.
Enforcement layer
MFA, access policy and session control for every login your IdP can't see.
Deployment
footprint
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. The DC Sensor runs on domain controllers, the DB agent on database hosts, and SSH and RDP go through one gateway.
Standing access
who holds the credential
Wraps existing creds
Wraps MFA and policy around the existing credential; JIT controls are part of its Privileged Access Security offering.
No standing access
Just-in-time plus the gateway: people never hold a long-lived credential. The vault holds it and rotates it.

Service accounts

Leads
Non-human identity security covering service accounts and AI agents, including discovery.
Excluded from push
Detected and excluded from push, so jobs keep running; fenced by policy to the hosts they run on, where supported.
Cloud / SaaS apps
SAML · OIDC
Leads
Cloud identity security across hybrid and cloud environments, not just on-prem.
Not in scope
Not in scope - AuthNull covers the on-prem logins your IdP can't see.
Privileged access
Leads 2 of 4
Just-in-time access
time-boxed admin rights
Yes
JIT controls are listed under its Privileged Access Security offering.
Yes
Request, approve by person or policy, get a window, and it expires - for servers and databases.
Session recording
SSH · RDP admin sessions
Not listed
Not listed among its published capabilities.
Yes
Every SSH and RDP admin session goes through one gateway, verified with MFA and recorded.
Conditional access policy
who · where · when
Yes
Risk-based authentication policy is a core part of its pitch.
Yes
Allow, MFA or deny by user, group, OU, source, time and machine - for on-prem AD, no Entra needed.
SSH key management

Not listed among its published capabilities.

Core pitch
the one-line pitch
Secure every identity
“Add MFA and risk-based policy to systems that can't natively support it” - now across human, non-human and AI identities.
No standing access
“MFA, access policy and session control for every login your IdP can't see.”
Best fit for
ideal buyer
Broad identity programme
Orgs buying one platform for identity risk across on-prem, cloud and non-human identities, with a team to run it.
Close the on-prem gaps
Orgs that need MFA, JIT and recorded admin sessions on AD, Linux, databases and network gear, live in days.

Authnull leads on 7 of 19 dimensions and ties on 9. Silverfort leads on the other 3 - Service accounts, Cloud / SaaS apps and ITDR (threat detection & response) - and if you need ITDR or cloud identity depth, it is the better buy.

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.
