Silverfort is a platform. Authnull is the layer that just closes the gap.
Silverfort genuinely pioneered agentless identity protection — and it's a serious, broad platform. But a platform is a project: an enterprise quote, a rollout, a security team to run it. If what you actually need is a factor on AD, RADIUS, Windows, and Linux — running this week, at a price you can see — that's a narrower job, and it's the one we do.
Both products live in the same place your IdP can't reach. The question isn't whether the gap gets covered — it's how much platform, time, and budget you want to spend covering it.
Silverfort didn't follow this category. It largely created it.
Agentless MFA on protocols that were never built to support it was a genuinely hard problem, and Silverfort solved it well. We're not going to wave that away — here's what it does that earns the respect.
Agentless by design
It inspects authentication traffic instead of installing on every endpoint — clever, and a real advantage in sprawling estates.
Service accounts & NHIs
Discovering and protecting non-human identities is a Silverfort strength, and most tools barely try.
ITDR depth
Identity threat detection and response across the estate is a whole product line. If you need that, it's real.
Enterprise scale
Proven in very large, very complex AD environments with the support and references to match.
So where do we come in? All of that is platform. Platforms get bought through procurement, scoped into a rollout, and operated by a team. A lot of organizations don't have that finding — they have one: enforce MFA on the infrastructure paths the auditor flagged. That's a smaller, sharper job, and it shouldn't require buying a platform to do it.
A platform you adopt, or a layer you switch on.
This isn't a coverage argument — Silverfort can cover these paths. It's a commitment argument. One is an enterprise platform decision; the other is a line item you can turn on this week and read the price of today.
Honest, dimension by dimension.
Both cover the identity gap — so this isn't a checkmark contest. It's about how the job gets bought, deployed, and run. Where Silverfort leads, we say so.
ITDR and non-human-identity governance are Silverfort's territory — Authnull coexists rather than competing there. The rows that decide a head-to-head are price, time-to-value, and how you buy.
One of these prices is on the page. The other needs a sales call.
Silverfort is sold as an enterprise platform — pricing is custom, quoted, and committed annually. We won't put words in their mouth with a made-up number. What we can do is show you exactly what Authnull costs at your size, right now.
Silverfort does not publish list pricing; figures are quoted per environment and we won't estimate them for you. Authnull bands shown are our published flat prices ($499/mo up to 500 identities, $900/mo up to 1,000 on-prem; SaaS $499/mo up to 500). Confirm any quote against your own paperwork — this worksheet is for scoping, not a contract.
Start narrow. Prove it on the audit finding. Expand only if you want to.
You don't need a platform decision to close an audit finding. Put Authnull on the paths that failed, see value in days, and decide the bigger questions later — with or without Silverfort in the picture.

Twenty minutes on your real environment — we'll tell you honestly whether a focused layer closes your gap or you genuinely need more. Or start free and enforce MFA on AD, RADIUS, Windows, and Linux this week.
