Scan identity and access daily, scan configuration and exposure weekly at minimum, run a full compliance assessment monthly, and re-scan immediately after any infrastructure change. That is the short answer. A cloud environment is not a static thing you photograph once a year. It drifts every day as engineers spin up resources, change defaults, and offboard users, so the right cadence is continuous for the fast-moving surfaces and scheduled for the slower ones.
Is a once-a-year cloud security assessment enough?
No. An annual assessment captures your posture on one day and says nothing about the other 364. Cloud config drifts constantly: a developer opens a storage bucket to hit a deadline, a default changes after a provider update, an admin leaves but their access lingers. Most cloud breaches trace back to misconfiguration, not a novel exploit, and a cloud misconfiguration introduced the week after your annual pentest sits exposed for eleven months before anyone looks again.
Compliance expectations have moved too. SOC 2 and ISO 27001 auditors increasingly want evidence of continuous monitoring across the audit period, not a snapshot from the week before fieldwork. "We ran a scan in March" no longer satisfies a Type II report.
What should you scan daily vs weekly vs monthly?
Split your cloud attack surface by how fast it changes and how badly it hurts when it breaks. Identity moves fastest and does the most damage, so it gets the tightest loop. Configuration and network exposure change often enough to warrant weekly. Framework mapping is heavier, so monthly is fine as long as the data feeding it stays fresh.
| Area | Recommended cadence | Why |
|---|---|---|
| Identity & access (privileged roles, MFA gaps, stale accounts, new service principals) | Daily / continuous | Changes hourly and is the fastest path to full compromise |
| Storage & network exposure (public buckets, open ports, exposed databases) | At least weekly, daily if you deploy often | One open resource is an immediate, internet-reachable breach |
| Workload & resource configuration (encryption, logging, key management) | Weekly | Drifts with every deploy and default change |
| Compliance posture (SOC 2, ISO 27001, CIS control mapping) | Monthly full assessment, fed by fresher underlying scans | Auditors want continuous evidence, not annual snapshots |
If daily scanning of everything is not realistic yet, prioritize identity and public exposure. Those two surfaces cause most cloud breaches and change the most between scans.
When should you re-scan outside the schedule?
Some events invalidate your last scan the moment they happen. Treat them as triggers rather than waiting for the next scheduled run:
- A new subscription, tenant, or account joins your estate. It arrived with zero coverage and provider defaults you did not choose.
- A major deployment or infrastructure change. New resources mean new potential misconfigurations your last scan never saw.
- A security incident. After containment, re-scan to confirm the exposure is actually closed and nothing else drifted during the response.
- Before an audit or a cyber-insurance renewal. Underwriters and auditors increasingly ask for current posture evidence, and a fresh scan avoids surprises in the room.
This is the gap scheduled scanning fills, and it is the recurring cadence platforms like SecValley automate so the daily and weekly runs happen without anyone remembering to press a button.
The takeaway
Pick cadences per surface instead of one blanket frequency: identity daily, exposure and configuration weekly, compliance monthly, and event-triggered re-scans on top. The goal is simple. No dangerous change to your cloud should survive longer than one scan cycle before someone sees it.
Frequently Asked Questions
Is continuous scanning the same as real-time scanning?
Not quite. Continuous scanning runs assessments on a tight recurring loop, often hourly or daily, so posture is never more than a cycle out of date. Real-time detection watches config-change and audit event streams and reacts within seconds. For most teams, continuous scheduled scanning plus event-triggered re-scans covers the risk without the cost and noise of full real-time monitoring.
How often do compliance frameworks require cloud scanning?
SOC 2 and ISO 27001 do not mandate a fixed interval, but a Type II audit expects evidence that controls operated continuously across the whole period, not on one day. In practice that means at least monthly assessments with fresher underlying data, kept as an ongoing record rather than a single annual snapshot.
What is the minimum viable scan cadence for a small team?
Scan identity and public exposure weekly and re-scan after every significant deploy. Those two surfaces cause most cloud breaches, so weekly coverage plus event triggers gets a small team most of the risk reduction of a heavier program. Add daily identity checks and monthly compliance mapping as capacity grows.
