The short version

  • Only Falco has a free tier, so it costs nothing to try first.
  • Each has a real cost: Entrust Identity as a Service the application integration catalogue is smaller than that of the dedicated identity vendors, so uncommon SaaS applications more often need custom SAML configuration rather than a template.; Falco falco detects and alerts but does not block; stopping an attack requires wiring up Falco Talon or your own response tooling, so out of the box a confirmed detection still means a human intervening after the fact.
  • They diverge on capability: Entrust Identity as a Service covers Multi-factor authentication, Falco covers eBPF kernel instrumentation.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Entrust Identity as a Service

  • A bank that must support hardware tokens for corporate treasury users alongside push authentication for staffnot Falco
  • An organisation already buying Entrust certificates that wants credential issuance and authentication from one vendornot Falco
  • A defence supplier required to use certificate-based authentication that mainstream cloud identity products handle poorlynot Falco

Falco

  • A platform team that needs to know when a shell is opened inside a production container, which image scanning cannot detect because it happens at runtimenot Entrust Identity as a Service
  • A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot Entrust Identity as a Service
  • A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot Entrust Identity as a Service
  • A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot Entrust Identity as a Service

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Entrust Identity as a Service

  • The application integration catalogue is smaller than that of the dedicated identity vendors, so uncommon SaaS applications more often need custom SAML configuration rather than a template.
  • Developer experience for customer identity use cases is behind the specialists, and teams building consumer signup flows will find the APIs and documentation less complete.
  • Advanced capabilities including adaptive authentication and credential management sit above the published entry price, so the two dollar figure rarely reflects what a regulated buyer actually spends.
  • There are two overlapping products, Identity as a Service and Identity Enterprise, and choosing wrongly at the start means a migration later rather than a licence change.
  • Identity governance, access certification and privileged access are not covered, so an organisation with audit-driven access review requirements needs a second vendor alongside it.

Falco

  • Falco detects and alerts but does not block; stopping an attack requires wiring up Falco Talon or your own response tooling, so out of the box a confirmed detection still means a human intervening after the fact.
  • The default rule set is noisy in real clusters and generates a large volume of benign matches from normal operational activity; without weeks of tuning, alert fatigue sets in and the team stops reading the feed, which is the usual failure mode.
  • There is no storage, console, search or case management in the project, so a working detection capability means also running Falcosidekick, an event store, a dashboard and alert routing, all of which you build, host and maintain.
  • The modern eBPF driver requires kernel 5.8 or later; older hosts fall back to the legacy probe or the kernel module, which brings driver-building against kernel headers and the operational fragility that comes with it on every kernel upgrade.
  • Per-node syscall instrumentation carries measurable CPU overhead on busy hosts, and the cost scales with syscall volume rather than with cluster size, so the noisiest and most performance-sensitive workloads are exactly the ones that feel it most.

Can I use Falco for free?
Yes. Falco has a free tier, so you can try it without paying. Entrust Identity as a Service starts at $2/month.
What is Entrust Identity as a Service best used for?
Entrust Identity as a Service is most often used for a government agency needing derived mobile credentials from an existing piv smart card estate, a bank that must support hardware tokens for corporate treasury users alongside push authentication for staff, an organisation already buying entrust certificates that wants credential issuance and authentication from one vendor, a defence supplier required to use certificate-based authentication that mainstream cloud identity products handle poorly. Of those, a government agency needing derived mobile credentials from an existing piv smart card estate and a bank that must support hardware tokens for corporate treasury users alongside push authentication for staff are not what Falco is typically brought in for.

Answered from the vendors’ own pages

Entrust Identity as a Service: Is MFA included or extra?

Multi-factor authentication is included in the workforce bundles rather than sold separately, which is not true of every competitor. Adaptive risk-based authentication sits in higher tiers.

Falco: Does Falco block attacks?

No. It detects and emits events. Response requires Falco Talon or your own automation on top.

Entrust Identity as a Service: Does it do identity governance?

No. Access certification, role mining and joiner-mover-leaver governance require a separate product such as SailPoint or Saviynt.

Falco: Is Falco owned by Sysdig?

Sysdig created and open sourced it, but it graduated within the CNCF in February 2024, so governance sits with the foundation rather than the vendor.

Entrust Identity as a Service: Why choose this over Okta or Entra ID?

Almost always because of PKI, smart cards or derived credentials. Without that requirement the mainstream platforms are the stronger general purpose choice.

Falco: What does it cost?

The project is Apache 2.0 with no licence fee. The cost is the storage, routing, tuning and staff time needed to make its output useful.

Falco: What kernel version do I need?

Kernel 5.8 or later for the default modern eBPF driver. Older hosts need the legacy eBPF probe or the kernel module.
