Managed security operations: continuous validation
Controls that were implemented correctly still drift. We keep them effective with a periodic check framework, weekly to annual, documented at every cadence.
Why this matters
Implemented is not the same as effective. Configurations drift, admin accounts pile up, alerts get tuned out, and backups quietly stop succeeding, unless someone is checking, on a schedule, and writing it down.
Silent configuration drift
A control that was correct at implementation can quietly stop being correct months later.
Alert fatigue
Untuned alerting drowns real signals in noise until nobody trusts the dashboard.
No evidence when it counts
Without documentation at every cadence, you have a memory of doing the work, not proof of it.
One-time assessments go stale
A posture assessment is a snapshot. Without ongoing checks, that snapshot ages fast.
What sets this apart
Continuous validation, not passive dashboard-watching. Our Periodic Security Check Framework assigns a defined activity to a defined cadence (weekly, monthly, quarterly, annual), each backed by a buildbook and a runbook your team reviews with us. Every check is actively validated and documented, not just glanced at on a dashboard.
- Every activity is scoped to your actual stack, not a generic checklist.
- A buildbook and runbook exist for every recurring activity.
- Findings feed a tracked remediation loop, not a one-off report.
- Documented evidence at every cadence, ready for your next audit.
The check log, cadence by cadence
Illustrative example of the log kept for a client; the exact activities are scoped to your stack.
- Weekly: solution uptime and authentication checked across the stack. Logged automatically; exceptions escalated the same week.
- Monthly: admin accounts and backup verification reviewed. Any stale account or failed job opens a tracked remediation item.
- Quarterly: compliance verification and configuration review completed. Findings roll into the quarterly maturity checkpoint with your team.
- Annual: roadmap and security posture evaluation refreshed. Feeds directly into your next assessment cycle.
What this covers
Four pillars, kept effective on an ongoing basis.
Continuous Control Assurance
Verify controls remain in place and effective, with configuration drift checks and periodic hardening reviews.
Security Operations Support
Monitoring, triage support and incident readiness, keeping your team prepared.
Vulnerability Management Ops
Scan, triage and remediation tracking: a closed-loop process with SLA targets, where a finding is closed only after a re-scan.
Governance Maintenance
Policy reviews, training updates and a quarterly maturity checkpoint with roadmap refresh.
Works with your stack
We work with what you already have. Common examples in scope, among others: EDR platforms, directory auditing, asset inventory, email security, network access control, SIEM, Microsoft 365, DNS filtering.
Getting started
Goal: a running cadence four weeks after scoping.
- Scope confirmation. Confirmation of the set of activities and frequency to be reviewed.
- Documentation. Create or update the buildbook and runbook for each activity.
- Review. Review the buildbook and runbook with your team.
- Start. Activities start running according to their assigned frequency.
With the other services
Managed Security Operations keeps your technical controls effective day to day; Security Governance and Reporting is the layer above it, proving to leadership, auditors and customers that the program is working. Most clients run both together. Implementation engagements (endpoint and server protection, vulnerability and patch management, identity and access) put the controls in place; this service keeps them effective. When an incident happens, incident response is available around the clock.
Controls that stay effective, not just controls that got implemented.
Let's talk about what a recurring review cadence would look like for your environment.
Frequently asked questions
- Do we need to have gone through an assessment first?
- It helps but is not required: we can scope directly against your current tool stack and controls. A posture assessment gives you a starting snapshot and a roadmap; the periodic check framework keeps that snapshot from aging, and the annual posture evaluation feeds directly into your next assessment cycle.
- What tools do you work with?
- Common examples in scope include EDR platforms, directory auditing tools, asset inventory, email security, network access control, SIEM, Microsoft 365 security and DNS filtering, among others. We work with what you already have; every activity is scoped to your actual stack, not a generic checklist.
- Which activities are checked, and on what cadence?
- Weekly, solution uptime and authentication across the stack; monthly, admin accounts and backup verification; quarterly, compliance verification and configuration review, which feed a maturity checkpoint; annually, the roadmap and security posture evaluation. Every check is documented, and any exception opens a tracked remediation item.
- Who attends the weekly reviews?
- Your designated IT or security contact and our operations team. The meeting is kept short and focused on the week's results (uptime, authentication, escalated exceptions), not a status-update ritual. Findings feed a tracked remediation loop, with a buildbook and a runbook reviewed with your team for every recurring activity.
- How does the service get started?
- In four steps, with the goal of a running cadence four weeks after scoping: confirmation of the set of activities and their review frequency; creation or update of the buildbook and runbook for each activity; review of those documents with your team; then activities start running according to their assigned frequency.
