What is the best open-source alternative to Keyfactor?

Infisical's core is open source under the MIT license, and Infisical can be self-hosted. Infisical covers private CAs, ACME, EST, and SCEP enrollment, discovery, renewal, and certificate syncs. Keyfactor Command is proprietary, and Keyfactor describes EJBCA Community Edition (the open source version of its private CA product) as not intended for production use.²

Do I need EJBCA to use Keyfactor Command?

You need EJBCA to issue private certificates from Keyfactor Command. Keyfactor Command also works with another CA you already run, such as Microsoft AD CS. Command manages certificates but doesn't issue them. Infisical has its own private CAs built in, which means it can issue and manage certificates in the same place.

Does Keyfactor support ACME?

Yes, but only through a separate Keyfactor ACME server that runs on IIS or Kubernetes with its own database. Infisical's ACME server is built into the platform, alongside EST and SCEP, which means it requires no separate infrastructure beyond a gateway deployed once on your infrastructure.

How long does it take to deploy Keyfactor Command?

In a Forrester study Keyfactor commissioned, the composite customer took about four months to deploy Command with five staff, then needed about two and a half full-time staff to run it.¹ Infisical runs as one platform with no separate enrollment servers to install.

Does Keyfactor Command need software on my network?

Yes. Self-hosted Command needs Microsoft SQL Server, plus Windows Server and IIS unless you run it on Kubernetes. Hosted Command needs Universal Orchestrators near your targets and a CA connector to reach on-premises CAs. Whether cloud- or self-hosted, any team using Keyfactor installs, patches, and monitors Keyfactor software. Infisical Cloud needs only one gateway to reach a private network.

How do I migrate from Keyfactor to Infisical?

Connect the CAs you issue from today, run discovery to build your inventory, then move enrollment and syncs one application at a time. Certificates you already track can be imported as PEM or PKCS#12.

Hey, sorry for the 2 AM call. Looks like the wildcard expired and took down the app, the API, the docs, everything.

Yeah, but the private key is still on his laptop.

ok we need to reissue from EJBCA, re-run orchestrator jobs on all hosts, and then import into Keyfactor Command because connection broke. At least the expiry alert worked this time lol

Sure, got it done.

What's the difference between Infisical and Keyfactor?

Infisical manages the full certificate lifecycle of any certificate on your infrastructure and lets you stand up your own CA hierarchy. Doing the same with Keyfactor requires implementing, maintaining, and integrating three different products.

Evaluate
Infisical
- Try the free tier to test-drive an internal CA, ACME, and the certificate dashboard
- Use the open-source version to audit and test the code
Keyfactor
- Lengthy sales process
- Quote and professional services before you start
- Can't audit all the code
Deploy/integrate
Infisical
- Use managed cloud, or self-host on Docker, Kubernetes, Linux, AWS ECS, or Google GKE
- One gateway to reach private networks
Keyfactor
- Stand up three products for different use cases and wire them together
- Install orchestrators and a CA connector on your network
- Requires Microsoft SQL Server to self-host
Migrate/onboard
Infisical
- Connect CAs you already issue from or create a new hierarchy in minutes
- Automatically discover every certificate on your network
- Set up syncs wherever they're needed
Keyfactor
- Spend four months deploying with five staff¹
- Buy professional services on top of the license
Control access
Infisical
- Sign in with whatever SSO you already use
- Set clear rules for visibility and access control
Keyfactor
- No native SAML: Sign in through Active Directory or OIDC
Operate
Infisical
- Keep one platform and gateway up to date
- Certificates renew automatically via API, SCEP, ACME, or EST
Keyfactor
- Patch Keyfactor Command, EJBCA, the ACME and SCEP servers, the orchestrators, and the CA connector
- Budget 2.5 full-time staff to run it¹
Automate
Infisical
- Get an email, Slack, PagerDuty, or webhook alert before anything expires
- Certificates land on consuming services with no agent to install
Keyfactor
- Manually wire up renewal alerts
- Build a renewal workflow before an alert can lead to a renewal
- Add an orchestrator extension for every kind of target
Scale
Infisical
- Sign code with approvals, without buying another product
- Add secrets, privileged access, or KMS on the same platform when you need them
Keyfactor
- Buy Signum for code signing
- Bring in another vendor for secrets management or other security infrastructure

Infisical vs. Keyfactor at a glance

Both Infisical and Keyfactor are capable certificate lifecycle management solutions. The biggest difference is in operational and deployment complexity.

Frequently asked questions

Everything you need to know. Can't find an answer? Talk to our team.

Yes. Infisical issues certificates from its own CAs or from any public and private CA you already use. It discovers certs on your network, renews them, syncs them to where they are served, and handles code signing. Keyfactor requires three different products (Command, EJBCA, and Signum) to do the same.

How to migrate from Keyfactor to Infisical

Most teams move one application at a time, so both systems run side by side until the last workload moves.

01
Connect your CAs
Connect the public and private CAs you issue from today or have your existing root sign an Infisical intermediate CA.
02
Build the inventory
Discover certificates across your networks and import the certificates Keyfactor tracks.
03
Move enrollment and delivery
Point ACME, EST, and SCEP clients at Infisical and replace orchestrator jobs with certificate syncs.
04
Retire Keyfactor
Once everything runs through Infisical, decommission Keyfactor.

Our team can help you plan and run the migration.
