Validate TLS Certificate Expiry Monitoring for Multi-Tenant Services with DeployClaw Frontend Dev Agent
Automate TLS Certificate Expiry Monitoring in AWS + SQL
The Pain
Most teams track TLS certificate expiries across multi-tenant AWS deployments using spreadsheets, email reminders, and tribal knowledge scattered across Slack threads. When a certificate approaches expiration, you rely on manual spot-checks of CloudFront distributions, ALBs, ACM, and API Gateway endpoints—each requiring separate AWS Console navigation. Teams miss renewal deadlines because tracking systems lack automation, certificate metadata lives in multiple data stores, and there's no centralized alerting tied to your deployment pipeline. When a certificate expires in production, you discover it during customer incidents rather than during your maintenance window. The window to perform graceful rollback shrinks from hours to minutes. Multi-tenant architectures compound this problem: a single overlooked certificate in one tenant's infrastructure cascades into widespread authentication failures. Database records of issued certificates drift from reality, creating audit gaps that compliance teams flag during reviews.
The DeployClaw Advantage
The Frontend Dev Agent executes certificate validation workflows using internal SKILL.md protocols that perform OS-level execution on your AWS environment and SQL backend. This isn't text generation—it's actual infrastructure introspection. The agent connects directly to AWS APIs, queries ACM certificate stores, inspects ALB and CloudFront listener configurations, and cross-references expiry dates against your SQL audit tables. It detects certificate chains nearing expiration (configurable thresholds: 30, 60, 90 days), identifies orphaned certificates no longer in use, and validates SAN (Subject Alternative Name) coverage across your multi-tenant domain matrix. The agent generates a deterministic report and can automatically trigger remediation workflows—requesting certificate renewal, scheduling pre-rotation validation, or blocking deployments that would use expired credentials.
Technical Proof
Before: Manual Certificate Validation
# SSH into bastion, run AWS CLI one service at a time
aws acm list-certificates --region us-east-1 | jq '.CertificateSummaryList[]'
# Manually inspect each certificate ARN in console
# Cross-check against CloudFront distributions via separate AWS call
# Query legacy SQL table for orphaned cert tracking
# Hope nothing was missed in previous quarter

Why This Matters
The agent completed a task that previously required 30+ minutes of manual console navigation, cross-referencing, and error-prone spreadsheet updates—all in under 4 seconds. It detected a SAN mismatch that would have caused validation failures during tenant-gamma's next deployment. It identified 3 orphaned certificates consuming ACM slots and costing unnecessary fees. Most critically, it flagged two certificates entering the critical renewal window, automatically initiating remediation so you renew before the production incident occurs, not after.
Your SQL audit tables remain synchronized with reality. Compliance reviews now reference deterministic agent logs instead of "we think we checked last month." Multi-tenant certificate matrices are validated at scale without human bottlenecks.
