sslbrain vs CertKit

Short answer

The CertKit agent is installed on each Windows and Linux server and delivers locally. An agent on one server can act as deployment hub and push to appliances and cloud services over API, SSH or CLI.^1,2 Each agent connects outbound over HTTPS to app.certkit.io. The private keys are kept in CertKit's cloud; in Enterprise they can also be kept on-prem.^3,4,5,6,7 Homelab, Professional and Business have public prices. Enterprise requires a sales conversation.¹

sslbrain runs as an appliance in your own network. The catalogue has 72 integrations. On Windows and Linux servers, a service agent installs the certificate. To network equipment and cloud services, the appliance pushes over API or SSH. Where there is no integration, you use a custom agent or ACME.

How to read the table

Every answer about another vendor carries a small number. It leads to the source at the foot of the page, with the date the source was last checked.
"Not stated" means it does not appear in the sources we reviewed. It does not mean no.
Prices are in the vendor's own currency, not converted. Where only the yearly or the monthly price is stated, the other is calculated and marked.
The sslbrain column has no source numbers. It comes from our own prices and our integration catalogue and links to those pages.

How the certificate gets there: Agents and push^1,2

Full answer

The CertKit agent is installed on each Windows and Linux server and delivers locally; an agent on one server is a deployment hub and pushes to appliances and cloud services via API, SSH or CLI. CertKit is itself an ACME client connecting to the CA, so the servers do not run ACME; ACME/SCEP for the customer's own clients is not mentioned. Automatic deployment is marked for all four plans
Direct agents and connectors: 56^8,9

Full answer

Automation

How the certificate gets there: Agents and push^1,2

Full answer

The CertKit agent is installed on each Windows and Linux server and delivers locally; an agent on one server is a deployment hub and pushes to appliances and cloud services via API, SSH or CLI. CertKit is itself an ACME client connecting to the CA, so the servers do not run ACME; ACME/SCEP for the customer's own clients is not mentioned. Automatic deployment is marked for all four plans
Direct agents and connectors: 56^8,9

Full answer

34 on-host destinations and 22 destinations to which an agent delivers from another machine; 20 of them are listed in 4.push, while Boomi API Gateway and Developer Portal require a manual "Upgrade to Latest" after each renewal according to the integration page, including Cisco ISE from Deployment Knowledge Base
Without a direct agent: Custom Deploy Template (reusable deployment configuration with a custom post-deploy script, also for appliances without a built-in template), basic templates with a post-deploy script, or retrieval from CertKit-hosted S3-compatible storage for collections without Keystore^12,6

SonicWall SonicOS 7.x (SonicOS API; SSL VPN and IPsec)¹⁶
WatchGuard Firebox (Fireware SSH CLI)³¹

What the list covers: Found in the integration page's sections "Network appliances" and "Containers and cloud", Deployment Knowledge Base and the reference architecture's push-host pattern. Only destinations with a built-in template where an agent on another machine delivers via API, SSH or CLI; on-host destinations (agent on the same server) and Custom Deploy Templates (the customer's own scripts) are not included. The vendor does not have one complete catalogue: Cisco ISE is listed only in Knowledge Base, WatchGuard only on the integration page, and other platforms are referred to Custom Deploy Templates^4,10

Private keys

Where the private key is kept: The vendor's cloud⁶
On-prem at the customer⁵

Network

Servers with an agent or ACME: As with the other plans: the agent initiates outbound HTTPS to app.certkit.io, no inbound ports from the internet^6,5,32

Full answer

DNS-01 via CNAME or HTTP-01 with port 80. With Keystore: Keystore listens on TCP 443 (can be changed), all agents must be able to reach it inbound, and Keystore itself has outbound HTTPS to CertKit
Equipment without an agent: The push-host agent on the customer's network initiates the connection to the device's management interface: HTTPS (F5, FortiGate, SonicWall, Kemp, FDM, Palo Alto, Ivanti; 443 or a specified port), Cisco ISE TCP 443, Juniper SRX REST TCP 3443 by default, IBM i RSE API normally port 2012, SSH/SCP to NetScaler, Aruba and WatchGuard (port not stated).^{9,29,27,15,25,6}

Full answer

Exception: ClearPass connects to the agent host on TCP 18080 to retrieve PFX. No inbound connection from the internet

Windows and Linux

Windows: The CertKit agent runs as a Windows service on the server, imports into Local Machine Store (My) or writes PFX and runs post-deploy PowerShell^3,11,10

Full answer

built-in templates bind IIS (site/port or SNI), RDP, Exchange, SQL Server, WinRM, AD FS and others. Outbound HTTPS to app.certkit.io (port number not stated)
Linux: The CertKit agent runs as a systemd service on the server, writes PEM files (cert.pem, key.pem, chain.pem), PFX or Java KeyStore and runs a post-deploy script^3,11,10

Full answer

built-in templates for nginx, Apache, HAProxy, PostgreSQL, MySQL, Postfix/Dovecot, Docker and others. Outbound HTTPS to app.certkit.io (port number not stated)

Branch offices

Remote sites and branch offices: As with the other plans (agent outbound to app.certkit.io, possibly via proxy; push-host per group of appliances).^3,5

Full answer

With Keystore, all agents, including those outside the data centre, must be able to reach the Keystore host on TCP 443

Vendor and EU

Vendor: TrackJS LLC, Minnesota limited liability company, Minneapolis, USA^33,7
Hosting and the EU: Primary infrastructure in Canada^34,33

Full answer

data may be stored and processed in Canada and other countries where CertKit or subcontractors operate. EU hosting or a choice of EU region is not stated

When CertKit fits better

You do not want to run a central server or gateway for certificate management: each agent connects outbound to CertKit's cloud on its own, and appliances get certificates from an agent on a host that can reach them.^3,4,6,7
