Security Scan 101: How to Audit Your AI App for High-Severity Flaws

Quick answer: A URL scan can report supported exposed-secret patterns, public-response signals, and configuration findings. SimplyScan grades 8 dimensions, including security, speed, and SEO. Use the report alongside source review and authorized tests of application-specific behavior; scan duration and coverage vary.

A rapid URL scan can add observations to a review of an application built with Lovable, Bolt.new, Cursor, or other tools. Choose checks that match the deployed resources you need to inspect, and review their coverage before drawing conclusions.

The risks are not theoretical.

These live figures describe all scanned sites. They do not establish prevalence for an AI-built subgroup, compare development methods, or attribute findings to AI generation.

30% of the 119 live sites SimplyScan has scanned (36 sites) have at least one high or critical security issue.

Investigate each high or critical finding to determine its impact. The scan figures do not establish how quickly an AI-built application was developed or whether another tool could assess it.

What Can a Security Scan Add to Your Review?

Review generated code and deployed configuration independently of visible feature behavior. Automated scans contribute supported observations; source review and authorized tests are needed for controls outside their scope.

For example, a working login form does not establish server-side authorization, CSRF protection, or safe session handling. Review those mechanisms directly; a header or URL scan cannot verify every authenticated flow.

11% of the 119 live sites SimplyScan has scanned (13 sites) have at least one medium-severity architecture issue, such as a library with a known vulnerability or no rate limiting.

How an app is structured deserves the same review as how it looks.

How Do You Run a Web Security Scan in 30 Seconds?

SimplyScan’s free URL scan typically takes about 30 seconds and requires no local installation. Timing depends on the target and checks.

Identify the Target URL

Use a reachable staging or production URL that you are authorized to assess.

Select the Relevant Checks

SimplyScan grades 8 dimensions using supported public-facing checks. Compare those checks with the evidence you need.

Analyze the Results

Look beyond simple pass/fail grades. A quality scan will categorize risks by severity, allowing you to prioritize fixing critical leaks before addressing minor performance issues.

Platform-focused guides such as Lovable and Cursor can help you review configuration; inspect the scan’s actual findings and coverage.

Which High-Severity Flaws Found in Scans Should You Check?

Investigate findings according to the evidence and affected permissions. A suspicious pattern is not automatically an exploitable vulnerability.

Exposed API Keys and Secrets

A secret embedded in public client code or requests is available to users inspecting those resources. Keep long-lived secrets in protected server-side configuration; exclude sensitive .env files from public assets and version control. Scanners recognize supported formats within their coverage. Revoke a real exposed credential, deploy a replacement, and investigate possible misuse.

Database Access Controls

For Supabase, review table privileges, RLS state, applicable policies, and bypass roles; disabled RLS alone does not grant access. For Firebase, review the Security Rules and IAM controls applicable to each service and client. Test intended allowed and denied operations. See RLS policies for PostgreSQL-specific guidance.

Security Headers

CSP can restrict selected browser behavior and help mitigate injection; HSTS directs supporting browsers to use HTTPS for a host. Review the effective policy and deployment rather than treating header presence as proof of protection.

29% of the 119 live sites SimplyScan has scanned (35 sites) have at least one medium-severity web-security issue, such as a missing Content-Security-Policy or HSTS header.

Investigate missing or weak header findings against the application’s requirements. This category figure does not identify which header, if any, is missing on your own site.

Can You Automate Security Scanning During Development?

Choose checks at relevant points in development and deployment. Source checks and deployed-URL checks require different inputs.

A compatible MCP client can invoke SimplyScan tools from an editor such as Cursor or Windsurf. URL checks require a reachable deployment. The separate Pro local-code tool uploads selected source files for supported checks; neither mode automatically fixes every issue or runs on each commit without workflow configuration.

Pro Monitoring includes Pro scan credits for full reports. See pricing for the allowance associated with your chosen option.

Automated monitoring can help detect some regressions after deployment; it does not prevent their introduction. SimplyScan Pro Monitoring provides uptime checks, scheduled rescans, and Slack or GitHub integrations.

How Does a Security Scan Differ from Antivirus Software?

It is important to distinguish between endpoint protection and application security. Antivirus software focuses on the device or the operating system, protecting against malware and local threats.

Web application checks inspect supported application resources and behavior, while endpoint protection focuses on the device. They address different risks. Neither a scan nor an endpoint product alone establishes that application logic and data are protected.

What Should You Do After a Scan Reports a Critical Issue?

A scan report is a roadmap, not just a warning. When a high-severity issue is identified, follow these steps:

Triage

Inspect the evidence and determine whether the reported condition affects your application. If a credential-like value is reported, determine its type and permissions; a JWT guide is relevant only if it is a JWT.

Mitigate

Contain the affected access or feature where appropriate. Revoke exposed credentials and review logs; choose measures suited to the actual service and incident.

Remediate

Fix the cause in code or configuration and test allowed and denied behavior. For Firebase services, review the applicable Security Rules and IAM controls.

Verify

Use an available rescan of the affected deployment and inspect whether the finding remains. Compare coverage and test the relevant control directly; a clean rescan does not prove every vulnerability has been removed.

Is It Possible to Get a Verified Security Badge?

A verified security badge links to a dated qualifying full site scan and its eligibility state. Review the badge criteria; it does not prove the absence of vulnerabilities.

Follow the verification link to inspect the scan date and current state.

Use the Scan as a Starting Point

Plan enough time to investigate findings and test controls beyond the scanner’s scope.

A free SimplyScan URL scan typically takes about 30 seconds and grades supported site signals, including security, speed, SEO, and compliance-related observations. It does not establish legal compliance.

Read the report’s coverage alongside its findings.

For applications built with Bolt or Windsurf, use relevant scans alongside source review and application-specific tests.

A Pro report provides additional finding details. Pro Monitoring separately offers scan credits, scheduled rescans, uptime checks, and supported integrations such as Slack and Linear. Review those features against the workflow you need.

Pro report costs $14.99 one-time.

Pro Monitoring costs $24/month.
