CertWatch vs TrackSSL
TrackSSL pioneered dedicated SSL monitoring, but it was built for static servers and IT administrators. CertWatch is built for dynamic infrastructure where pods die, IPs change, and configuration lives in Git. Open-source agent. 1-minute intervals. GitOps-native.
The Generational Divide: IT Admin vs DevOps
TrackSSL has been monitoring certificates since the data center era. They've built a solid product used by companies like Dell and IBM.
But the infrastructure landscape has fundamentally changed:
| 2015 (TrackSSL Era) | 2025 (CertWatch Era) |
|---|---|
| Static servers with fixed IPs | Ephemeral pods with dynamic IPs |
| Manual certificate deployment | Automated cert-manager renewals |
| Web UI configuration | GitOps / Infrastructure-as-Code |
| Quarterly deployments | Continuous deployment |
| IT administrator workflow | DevOps/SRE workflow |
TrackSSL was built for a world where servers had names and stayed in one place. CertWatch is built for a world where infrastructure is code.
Head-to-Head Comparison
| Capability | TrackSSL | CertWatch |
|---|---|---|
| Private Agent Check Interval | Every 4 hours | Configurable (1 min - 24 hrs) |
| Agent Source Code | Viewable only (not open-source) | Fully open-source (MIT) |
| Free Tier | 2 certificates | Free during beta |
| Kubernetes Deployment | Docker container | Native Helm chart |
| Configuration Style | Web UI | YAML + CLI (GitOps) |
| State Persistence | Unknown | Smart migration for pod restarts |
| Prometheus Metrics | ❌ No | ✅ Built-in /metrics endpoint |
| Webhooks | $72+/month plan only | Included on all plans |
| API Access | $35+/month plan only | Included on all plans |
| CT Log Monitoring | Coming Soon | Coming Soon |
The Agent Problem: 4 Hours vs 1 Minute
TrackSSL's private monitoring agent checks certificates every 4 hours. In Kubernetes, that's an eternity.
Real-World Scenario: Bad Deployment
09:00 - You deploy a new release
09:01 - Deployment accidentally overwrites certificate secret
09:02 - Production is serving with invalid cert
09:05 - CertWatch alerts: "Certificate chain invalid"
13:00 - TrackSSL finally checks... 4 hours of broken production
In a world of continuous deployment, 4-hour check intervals are a liability.
CertWatch's agent supports configurable intervals down to 1 minute—that's 240× more frequent than TrackSSL for your most critical endpoints.
Open Source vs "Source Available"
TrackSSL describes their agent as having "viewable" source code for security audits. This is not open source.
| Aspect | TrackSSL Agent | CertWatch Agent |
|---|---|---|
| Source Code | Viewable (read-only) | Open-source (MIT License) |
| Can You Fork It? | ❌ No | ✅ Yes |
| Can You Contribute? | ❌ No | ✅ Yes (PRs welcome) |
| Can You Audit? | ✅ Yes | ✅ Yes |
| Can You Self-Host Forever? | ❌ No | ✅ Yes |
Why this matters:
- Security Audits: Your security team can verify exactly what the agent does
- Custom Extensions: Add support for your specific TLS endpoints
- No Vendor Lock-in: If CertWatch disappears, the agent keeps working
- Community Improvements: Benefit from contributions by other users

Kubernetes-Native Architecture
TrackSSL's agent is distributed as a Docker container—it works in Kubernetes, but it wasn't designed for it.
CertWatch's agent was built for Kubernetes from day one:
The Ghost Agent Problem
In Kubernetes, pods are ephemeral. They get scheduled, killed, rescheduled, scaled up, scaled down. If your monitoring agent generates a new ID every time it restarts, your dashboard fills with "ghost" entries:
cw-agent-7f8d9-abc12 [OFFLINE] - Last seen 3 days ago
cw-agent-7f8d9-def34 [OFFLINE] - Last seen 2 days ago
cw-agent-7f8d9-ghi56 [OFFLINE] - Last seen 1 day ago
cw-agent-7f8d9-jkl78 [ACTIVE] - Current pod
CertWatch's Solution: Smart State Migration
The cw-agent persists state to .certwatch-state.json and intelligently migrates certificates when agents restart or get renamed. Your dashboard stays clean, and historical data follows the logical agent identity—not the ephemeral pod ID.
Helm Chart Deployment
# TrackSSL: Manual Docker deployment
docker run -d trackssl/agent ...
# CertWatch: GitOps-native Helm deployment
helm repo add certwatch https://charts.certwatch.app
helm install cw-agent certwatch/cw-agent \
--set agent.apiKey=$CERTWATCH_API_KEY \
--values certwatch-values.yaml
Store certwatch-values.yaml in your Git repository. Deploy with ArgoCD or Flux. Configuration as code.
Pricing: The Microservices Tax
TrackSSL charges per certificate. This model breaks down in microservices architectures.
TrackSSL Pricing
| Plan | Certificates | Price |
|---|---|---|
| Free | 2 | $0 |
| Starter | 20 | $17/month |
| Professional | 50 | $35/month |
| Complete | 200 | $72/month |
The Problem
In a typical Kubernetes cluster:
- 50 microservices × 3 environments (dev/staging/prod) = 150 internal certs
- Plus your public domains, databases, message queues...
Under TrackSSL, monitoring your internal infrastructure costs $72+/month minimum—and that's before your public domains.
CertWatch Pricing
| Tier | Certificates | Price |
|---|---|---|
| Free | Limited | $0 |
| Beta | Generous limits | $0 (limited time) |
| Post-Beta | TBD | Volume-based |
Generous free tier during beta. That's enough to monitor your entire internal infrastructure while you evaluate.
Feature Gating
| Feature | TrackSSL | CertWatch |
|---|---|---|
| Webhooks | $72+/month only | All plans |
| API Access | $35+/month only | All plans |
| Private Agent | $72+/month only | All plans |
| Slack/Teams | All plans | All plans |
CertWatch doesn't gate essential features behind enterprise pricing.
Configuration Philosophy: UI vs GitOps
TrackSSL is built around a web UI. You log in, click "Add Domain," fill in a form.
CertWatch is built around configuration as code:
TrackSSL Workflow
- Log into web UI
- Click "Add Domain"
- Fill in form fields
- Click Save
- Repeat for each domain
- Hope someone documented this in Confluence
CertWatch Workflow
# certwatch.yaml - lives in your Git repo
api_key: ${CERTWATCH_API_KEY}
agent:
name: production-cluster
endpoints:
- address: api.example.com:443
alert_thresholds:
warning: 30d
critical: 7d
- address: postgres.internal:5432
protocol: tls
- address: kafka.internal:9093
protocol: tls
# Deploy with your application
git commit -m "Add kafka certificate monitoring"
git push
# ArgoCD/Flux deploys automatically
Benefits:
- Version controlled (who changed what, when)
- Code review for monitoring changes
- Same workflow as your application code
- Reproducible across environments
Security Architecture
Both TrackSSL and CertWatch use outbound-only connections for their agents. But CertWatch goes further:
Distroless Container
The cw-agent is compiled as a static Go binary and runs in a distroless container:
FROM gcr.io/distroless/static:nonroot
COPY cw-agent /
USER nonroot:nonroot
ENTRYPOINT ["/cw-agent"]
What this means:
- No shell (
/bin/sh,/bin/bash) - No package manager (
apt,apk) - No unnecessary OS utilities
- Minimal attack surface
If an attacker somehow compromises the agent container, they find:
- No shell to execute commands
- No tools to download malware
- No way to pivot to other systems
This "secure by design" approach matters to security teams evaluating monitoring tools.
What TrackSSL Does Well
Let's be fair—TrackSSL has strengths:
- Established track record: Years in production at major companies
- UI for non-technical users: Good for marketing/IT teams who prefer clicking over YAML
- Mobile notifications: Push notifications via mobile app
- Detailed certificate analysis: Good visualization of certificate details
If your team prefers UI-driven workflows and doesn't need Kubernetes-native features, TrackSSL is a solid choice.
When to Choose CertWatch
CertWatch is the better choice if:
- ✅ You run Kubernetes or container-based infrastructure
- ✅ You practice GitOps / Infrastructure-as-Code
- ✅ You need check intervals faster than 4 hours
- ✅ You want to monitor 50+ internal certificates without enterprise pricing
- ✅ You prefer open-source tools you can audit and extend
- ✅ You want Prometheus metrics for your existing dashboards
- ✅ You need webhooks/API without paying $35-72/month
Migration Path: TrackSSL → CertWatch
Step 1: Export Your Domains
TrackSSL doesn't have a bulk export, but you can list your domains in the UI and manually compile them.
Step 2: Create certwatch.yaml
api_key: ${CERTWATCH_API_KEY}
agent:
name: production
endpoints:
# Your TrackSSL domains
- address: example.com:443
- address: api.example.com:443
- address: dashboard.example.com:443
# Now add internal endpoints TrackSSL couldn't monitor efficiently
- address: postgres.internal:5432
protocol: tls
- address: redis.internal:6379
protocol: tls
check_interval: 5m # vs TrackSSL's 4 hours
Step 3: Deploy
# Interactive setup wizard
cw-agent init
# Or direct deployment
helm install cw-agent certwatch/cw-agent --set agent.apiKey=$KEY
Step 4: Run Both in Parallel
We recommend running CertWatch alongside TrackSSL for 1-2 weeks to validate alerts. Once you're confident, cancel TrackSSL.
