Pros & Cons
CertKit
Pros
Free Community tier makes it easy to evaluate the platform's core discovery and monitoring capabilities without cost.
Deployment via a single agent to a wide range of servers and network appliances, without needing ACME configured everywhere, simplifies rollout across heterogeneous infrastructure.
Certificate Transparency-based discovery surfaces forgotten or unauthorized certificates that manual tracking would likely miss.
Generous 90-day free trial on paid tiers with no credit card required lowers the barrier to a full evaluation.
Purpose-built and narrowly focused on certificate lifecycle management rather than being a small feature bolted onto a broader security suite.
Cons
A relatively new product, launched in 2024, with less of a long-term track record than established certificate lifecycle management vendors.
Small company (TrackJS LLC) behind the product means less scale of support and resources compared to larger enterprise security vendors.
Free and entry-level paid tiers cap certificate and agent counts fairly low (2 and 10 respectively), meaning larger organizations will need Business or Enterprise pricing quickly.
Enterprise pricing is custom and not published, requiring a sales conversation for large-scale or multi-tenant deployments.
As with any tool crawling Certificate Transparency logs, discovery is limited to publicly logged certificates and won't surface internal-only or private CA-issued certificates not logged publicly.
Grype
Pros
Free and open source under Apache-2.0
Broad ecosystem support across OS packages and multiple programming languages
Vulnerability prioritization via EPSS and KEV reduces noise
Multiple install methods, including curl, Homebrew, Docker, Chocolatey, and MacPorts
Active GitHub community with 12.6k+ stars
Cons
Command-line tool with no built-in graphical dashboard
Some workflows require pairing with a separate SBOM tool like Syft
No official managed or hosted service documented
Use Cases
CertKit
Preventing certificate-expiration outages — IT teams use CertKit's monitoring and automated renewal to eliminate the risk of a forgotten certificate expiring and taking down a production service unexpectedly.
Auditing an organization's full certificate footprint — Security teams use CertKit's Certificate Transparency-based discovery to build a complete inventory of every certificate issued for their domains, including ones issued outside official processes.
Managing certificates across multiple client environments — Managed service providers use CertKit's multi-tenant Enterprise tier to centrally track and automate certificate lifecycle management across many separate client infrastructures.
Grype
Container image vulnerability scanning — Teams scan container images before deployment to catch known CVEs.
SBOM-based vulnerability analysis — Security teams scan SBOM files generated by tools like Syft to assess dependency risk without rescanning images.
CI/CD vulnerability gating — Engineering teams add Grype scans to pipelines to block builds with critical vulnerabilities.
