How to Monitor Lacework with Vigilmon

Lacework provides cloud-native security for workloads, containers, and cloud accounts — detecting threats, misconfigurations, and anomalies across your infrastructure. Lacework's value is entirely realized through its alerting pipeline: when Lacework detects a threat, it fires a webhook or forwards an alert to your SIEM, Slack, or PagerDuty. If that alerting pipeline is broken, Lacework keeps detecting but your team never hears about it. Vigilmon gives you external monitoring of the downstream endpoints that Lacework fires alerts to, as well as any Lacework API integrations you've built — so a broken webhook or unreachable alert receiver is caught before a real threat goes unnoticed.

What You'll Build

• A monitor on your Lacework webhook receiver to detect silent alert drops
• Health checks on downstream alert sinks (Slack, PagerDuty, SIEM endpoints)
• A monitor on any Lacework API integration service you operate
• SSL certificate monitoring for your alert receiver infrastructure
• An alerting setup tuned to the criticality of a security alerting pipeline

Prerequisites

• A Lacework account with at least one alert channel configured (webhook, Slack, PagerDuty, or custom)
• An HTTP-accessible webhook receiver or integration service
• A free account at vigilmon.online

Step 1: Understand the Lacework Alerting Architecture

Lacework's detection engine is a SaaS service — you don't operate it directly. What you operate (and what can fail) is the downstream pipeline:

1. Lacework outbound webhooks: Lacework POSTs alert payloads to a URL you register. If your receiver is down, the webhook delivery fails and Lacework may retry — but retries are finite.
2. Alert channel integrations: Slack, PagerDuty, Jira, and SIEM integrations forward Lacework alerts to your tools. If the integration endpoint is unreachable, alerts are dropped.
3. Custom Lacework API services: If you've built services using the Lacework SDK or REST API to pull alerts, policies, or compliance data, those services can fail independently.
4. Lacework agent sidecar services: If your deployment pipeline installs Lacework agents via a bootstrap service, that service's availability affects agent deployment coverage.

Monitoring these downstream components ensures that when Lacework detects something, your team actually finds out.

Step 2: Monitor Your Lacework Webhook Receiver

If you use Lacework's webhook alert channel, your receiver must be reachable for Lacework to deliver alerts. Expose a health endpoint on your receiver:

# FastAPI example
from fastapi import FastAPI, Request

app = FastAPI()

@app.get("/health")
def health():
    return {"status": "ok", "service": "lacework-receiver"}

@app.post("/lacework/alerts")
async def receive_alert(request: Request):
    payload = await request.json()
    # Process alert: log, enrich, forward to SIEM
    return {"processed": True}

Register this receiver URL in the Lacework console under Settings → Alert Routing → Add New → Webhook, using https://receiver.example.com/lacework/alerts.

Add a Vigilmon monitor for the health endpoint:

1. Log in to Vigilmon → Add Monitor → HTTP.
2. URL: https://receiver.example.com/health.
3. Check interval: 60 seconds.
4. Response timeout: 10 seconds.
5. Expected status: 200.
6. Keyword: "status":"ok".
7. Label: Lacework webhook receiver.
8. Click Save.

Alert after: 1 consecutive failure. A downed receiver means Lacework threat alerts are silently dropped.

Step 3: Monitor Downstream Alert Sinks

Lacework integrates with Slack, PagerDuty, and other services. Monitor these endpoints directly to catch configuration drift (deleted webhooks, revoked keys) before a real alert fails to deliver.

Slack incoming webhook:

Slack returns 405 Method Not Allowed on a GET request to a valid webhook URL (the expected behavior):

1. Add Monitor → HTTP.
2. URL: https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX.
3. Check interval: 5 minutes.
4. Expected status: 405 (confirms the webhook exists; 404 means deleted).
5. Label: Lacework Slack webhook.
6. Click Save.

PagerDuty Events API:

PagerDuty returns 400 Bad Request on a bare GET (payload required) — which confirms the endpoint is reachable:

1. Add Monitor → HTTP.
2. URL: https://events.pagerduty.com/v2/enqueue.
3. Check interval: 5 minutes.
4. Expected status: 400.
5. Label: PagerDuty Events API (Lacework).
6. Click Save.

Custom SIEM endpoint (e.g., a Splunk HEC collector):

curl -I https://splunk.example.com:8088/services/collector/health

Splunk HEC returns 200 with {"text":"HEC is healthy","code":17} when operational:

1. Add Monitor → HTTP.
2. URL: https://splunk.example.com:8088/services/collector/health.
3. Check interval: 2 minutes.
4. Expected status: 200.
5. Keyword: HEC is healthy.
6. Label: Splunk HEC (Lacework).
7. Click Save.

Step 4: Monitor Your Lacework API Integration Service

If you've built a service that uses the Lacework REST API or SDK to pull alerts, compliance reports, or policy data:

curl https://integration.example.com/api/lacework/health

Example health response:

{
  "status": "ok",
  "lacework_api": "connected",
  "last_sync": "2026-07-03T04:00:00Z"
}

Add a monitor:

1. Add Monitor → HTTP.
2. URL: https://integration.example.com/api/lacework/health.
3. Check interval: 5 minutes.
4. Expected status: 200.
5. Keyword: "lacework_api":"connected".
6. Label: Lacework API integration.
7. Click Save.

API token expiry: Lacework API tokens have a configurable TTL. When a token expires, your integration service will fail with 401 errors. Add a check for the last_sync timestamp to detect when the service has stopped fetching data, even if the health endpoint returns 200.

Step 5: Monitor Agent Bootstrap Services

If your infrastructure uses a service to deploy and register Lacework agents on new hosts or containers:

curl https://agent-bootstrap.example.com/health

{
  "status": "ok",
  "agents_registered_24h": 12
}

Add a monitor:

1. Add Monitor → HTTP.
2. URL: https://agent-bootstrap.example.com/health.
3. Check interval: 5 minutes.
4. Expected status: 200.
5. Keyword: "status":"ok".
6. Label: Lacework agent bootstrap.
7. Click Save.

Step 6: Monitor SSL Certificates

All Lacework webhook and API endpoints require valid TLS. An expired certificate on your receiver causes Lacework's outbound webhook to fail with TLS errors — alert delivery silently stops:

openssl s_client -connect receiver.example.com:443 2>/dev/null | openssl x509 -noout -dates

Add certificate monitors:

1. Add Monitor → SSL Certificate.
2. Domain: receiver.example.com.
3. Alert when expiry is within: 30 days.
4. Alert again: 14 days, 7 days, 3 days, 1 day.
5. Click Save.

Repeat for each domain in your alert pipeline: integration.example.com, splunk.example.com, agent-bootstrap.example.com.

Step 7: Configure Alerting

In Vigilmon under Settings → Notifications, configure your alert channels:

| Monitor | Trigger | Action | |---|---|---| | Webhook receiver | Non-200 or keyword missing | Restart receiver service; check error logs; review Lacework delivery logs | | Slack webhook | 404 (not 405) | Webhook deleted — re-create in Lacework console and Slack | | PagerDuty Events API | Unexpected status | Check PagerDuty status page; verify routing key is valid | | Splunk HEC | Non-200 or HEC is healthy missing | Check Splunk indexer health; verify HEC token | | Lacework API integration | Non-200 or keyword missing | Check API token validity; review integration service logs | | SSL certificates | < 30 days to expiry | Renew certificate; check ACME or certificate automation |

Alert routing: All alerts from Lacework pipeline monitors should go to your security team with high severity — a broken alerting pipeline is itself a security incident.

Common Lacework Pipeline Failure Modes and What Vigilmon Catches

| Scenario | Vigilmon monitor | |---|---| | Webhook receiver process crash | Receiver monitor fires; Lacework alert delivery fails | | Slack webhook deleted by accident | Slack webhook monitor returns 404 instead of 405 | | Lacework API token expired | API integration monitor fails keyword check (no connected status) | | Splunk HEC indexer down | HEC health monitor fires; alerts not reaching SIEM | | TLS cert expired on receiver | SSL monitor alerts at 30-day threshold; Lacework can't POST alerts | | PagerDuty integration broken | Events API monitor detects unexpected status | | Agent bootstrap service down | Agent registration stops; new hosts have no Lacework coverage |

A Note on Lacework SaaS Availability

Lacework's detection platform itself is a SaaS product — you can monitor its published status page and API endpoints to be notified of platform-side incidents:

1. Add Monitor → HTTP.
2. URL: https://status.lacework.com/ (or Lacework's published status API if available).
3. Check interval: 5 minutes.
4. Expected status: 200.
5. Label: Lacework platform status.
6. Click Save.

This gives you independent visibility into Lacework platform incidents separate from your own receiver and integration health.

Lacework is only as effective as the pipeline that delivers its alerts. When a webhook receiver goes down, a Slack integration is accidentally deleted, or a SIEM HEC endpoint becomes unreachable, Lacework keeps detecting threats — but your team stops hearing about them. Vigilmon closes that gap with external monitoring of every downstream endpoint your Lacework deployment depends on, so broken alert delivery is caught immediately rather than discovered during a post-incident review.
