How Often Should You Scan Your Website for Vulnerabilities?

The short answer: continuously, not annually

For most small and medium businesses, the right frequency to scan a website for vulnerabilities is continuously, with automated scans running at least weekly, supplemented by an immediate scan after every code deployment or major configuration change. An annual scan, or worse, a one-time scan before launch, leaves a business exposed for months at a time to vulnerabilities that did not exist when the last check ran.

This is not a scare number designed to sell more scans. It reflects how the threat landscape actually moves. New vulnerabilities are disclosed daily, website code changes constantly, and attackers use automated tools to find exposed systems within hours of a new exploit going public. A scan is a snapshot: the moment it finishes, it starts going stale.

Why this matters for small and medium businesses

Larger enterprises often run daily or even continuous scanning because they have dedicated security teams and budgets to match. Small businesses assume they can get away with less because they are "too small to be a target." That assumption is backwards, and it is one of the most common reasons SMBs get breached.

According to Verizon's Data Breach Investigations Report, small businesses are involved in a large and growing share of confirmed breaches every year, and attackers increasingly automate their reconnaissance rather than hand-picking targets. A vulnerable WordPress plugin, an exposed admin panel, or an unpatched framework gets found by a scanning bot, not a human being deciding your company is worth the effort. Frequency of scanning is your best defense against being caught by that automation.

There is also a cost-of-delay problem. IBM's Cost of a Data Breach Report consistently shows that breaches which take longer to identify and contain cost significantly more than those caught quickly. A vulnerability sitting unpatched for eleven months because it was only checked once a year is a vulnerability with eleven months to be exploited, sold on a dark web forum, or chained with another flaw into a full breach.

How to think about scan frequency by scenario

Different situations call for different cadences. Use this as a practical baseline and adjust upward, never downward, based on your risk profile.

Baseline: weekly automated scans

Every public-facing website and web application should have an automated vulnerability scan running at least once a week. This catches:

• Newly disclosed CVEs affecting your CMS, plugins, or frameworks
• Configuration drift introduced by routine maintenance
• Expired SSL certificates or newly exposed services
• Regressions where a previously fixed issue reappears

Weekly is the minimum that keeps your exposure window measured in days rather than months.

After every deployment

Any time code ships to production, whether it is a new feature, a bug fix, or a third-party plugin update, run a scan immediately afterward. Deployments are the single most common moment when new vulnerabilities get introduced, because new code paths, new dependencies, and new configuration options all arrive at once.

After adding new infrastructure

New subdomains, staging environments left publicly accessible, new API endpoints, and newly connected third-party integrations all expand what attackers can target. Each addition to your attack surface should trigger discovery and scanning, not wait for the next scheduled cycle.

Immediately after a disclosed CVE affecting your stack

If a critical vulnerability is publicly disclosed in a technology you use (a CMS core, a popular plugin, a web server), do not wait for your weekly cycle. Scan immediately. Attackers move within hours of public disclosure, and so should you.

Before and after major traffic events

Product launches, marketing campaigns, and seasonal sales (Black Friday, holiday shopping) attract both legitimate traffic and opportunistic attackers. Scan in the days before to confirm a clean baseline, and again shortly after to catch anything introduced under the pressure of a rushed launch.

What "scanning" actually needs to cover

Frequency only helps if the scan itself is thorough. A narrow scan run daily is less useful than a comprehensive scan run weekly. Make sure your scanning approach checks for:

1. OWASP Top 10 issues — SQL injection, cross-site scripting (XSS), broken authentication, security misconfigurations, and the rest of the industry-standard vulnerability categories
2. Known CVEs in your CMS, plugins, frameworks, and any software your site depends on
3. Misconfigurations — exposed admin panels, default credentials, directory listing left enabled, missing security headers
4. Subdomains, not just your primary domain — forgotten staging sites and old marketing pages are common entry points
5. SSL/TLS configuration — expired or weak certificates undermine every other control you have in place

Common mistakes to avoid

• Scanning once before launch and never again. A website is never "finished." Every update is a new opportunity for a vulnerability to slip in.
• Only scanning the main domain. Subdomains, staging environments, and old marketing microsites are frequently forgotten and frequently exploited.
• Treating a clean scan as a permanent guarantee. A scan result is accurate for the moment it runs. New CVEs are disclosed daily against the exact software stacks most businesses run.
• Waiting for a compliance audit to trigger scanning. Compliance-driven annual scans are a floor, not a strategy. They exist to satisfy auditors, not attackers.
• Ignoring low and medium severity findings. Attackers routinely chain several "minor" issues together to achieve a critical outcome. What looks low-risk in isolation is not always low-risk in combination.
• Not scanning after third-party plugin or dependency updates. Updates fix some issues and occasionally introduce new ones. Every update deserves a follow-up check.

How Volturion helps

Volturion runs automated vulnerability scans on a recurring schedule matched to your plan, so your exposure window never stretches into months. Every scan checks for OWASP Top 10 issues, known CVEs affecting the frameworks and plugins your site runs, and common misconfigurations, then maps each finding to its severity and the specific CWE and OWASP category involved.

Because attack surface changes constantly, Volturion also automatically discovers new subdomains connected to your monitored domains and brings them into the same scanning schedule, so forgotten staging sites and old marketing pages do not become blind spots. For every vulnerability found, Volturion's AI generates a specific, step-by-step remediation plan tailored to your tech stack, so your team can close the gap immediately rather than waiting for a security consultant's next available slot. Real-time alerts via email, Slack, Discord, or webhook mean you find out about a new critical finding within minutes of it being detected, not at the next scheduled review.
