Silverfort review

Silverfort is an identity security platform for human, machine, and AI identities. It discovers identities across an organization and analyzes access requests, then can allow, challenge, or block them in real time before access is granted. The product description says this works without system modifications.

That makes Silverfort broader than a tool that adds MFA to one sign-in screen. Its listed capabilities include identity discovery, runtime enforcement, universal MFA for legacy apps, command-line tools, and OT infrastructure, plus controls for privileged access and Active Directory. It also says it can discover, monitor, and secure AI agents and other non-human identities.

For organizations with older systems or a mix of identity types, the pitch is centralized enforcement without installing agents or changing application code. Silverfort lists four plans—Core, Plus, Advanced, and Enterprise—but plan-by-plan features are not published on the vendor's site. That makes it difficult to tell which capabilities require which tier.

Silverfort’s clearest strength is breadth across authentication paths. Its listed features cover legacy applications, command-line tools, OT infrastructure, Active Directory, privileged access, and non-human identities. The product description says it can enforce access decisions in real time without agents or code changes—useful in environments where adding software to every server or modifying each application is impractical.

That wider reach comes up in user discussions, though reports are anecdotal. One r/sysadmin commenter said Silverfort operates at the AD authentication layer and described protecting logins using Kerberos, LDAP, and NTLM, including remote PowerShell and file shares. Another commenter contrasted broader protocol coverage with MFA that only protects RDP. These comments suggest why teams with legacy or hybrid environments consider it for more than interactive logins.

The feature set also extends beyond MFA: Silverfort lists identity discovery, dynamic privileged access controls, least privilege, and just-in-time access without a vault. It specifically includes AI agents and other non-human identities. For an organization trying to cover human and service identities under one runtime policy model, that scope is a meaningful advantage—provided its policies fit the organization’s workflows.

The biggest drawback is price opacity. Available pricing information describes quote-based pricing by organization size, but gives no monthly or annual rates, per-user price, or published unit. Core, Plus, Advanced, and Enterprise are all listed without feature breakdowns. A Reddit user reported that their organization was below Silverfort’s minimum purchase, but the minimum itself is not published. We can’t say what a smaller buyer would pay or which plan it would need.

Support adds cost: the listed Premier support add-on is 10% of license cost, Diamond is 20%, and Expert Services pricing is not published. Pricing confidence is low, so buyers should confirm all figures and minimums directly. The published information does not state whether a free trial is available.

Policy work is another caveat. In one r/sysadmin thread, a user said policies needed massaging and that service accounts were still being sorted out; another said pricing pushed them toward Authlite for admin MFA. A separate commenter said their evaluation did not offer a self-serve test, while another reported a proof of concept in a development domain. Plan for policy validation, and ask for a hands-on evaluation before committing.

Silverfort does not publish list prices. Its pricing is quote-based by organization size, and the available information names four tiers—Core, Plus, Advanced, and Enterprise—without prices or included features. That means there’s no published dollar jump between tiers, and no way to compare their value before requesting a quote.

Monthly and annual rates are also not published, so ask whether the quote changes with billing term, identity count, or deployment scope. The listed support add-ons are more concrete: Premier support costs 10% of the license cost, while Diamond support costs 20%. Expert Services pricing is not published. Because those percentages are tied to an undisclosed license price, their actual cost is also unclear until Silverfort quotes your organization.

The published pricing information lists no free plan; trial availability is not published. Get the tier inclusions, billing terms, support costs, and renewal terms in writing before comparing Silverfort with another identity security platform.

Silverfort says it can enforce access in real time without system modifications, and its Active Directory protection is described as working without agents or code changes. That may reduce one part of deployment, but the published material doesn’t spell out implementation effort, integrations, policy migration, or how long rollout takes. Plan time to map identities and decide which access requests should be allowed, challenged, or blocked; exact requirements are not published.

Before signing, ask what identity and policy data can be exported, in what format, and whether those exports remain usable if you leave. Export options and portability terms are not published on the vendor's site, so don’t assume a clean exit.

We weren’t given Reddit posts or comments to support claims about why customers leave Silverfort, so we can’t attribute churn reasons to users. The practical reasons to investigate are the same ones that complicate a switch: unclear pricing, unconfirmed data portability, and the policy work required to replace runtime enforcement. Get those answers from Silverfort before committing.
