A useful website security check is a staged process: confirm you are authorized to test the target, map its public attack surface, verify HTTPS and HSTS, review application controls, run automated scans, manually validate findings, fix confirmed weaknesses, and repeat the checks. A certificate or one-click scanner can reveal problems, but neither proves that an application is secure.
1. Confirm authorization and define the scope
Test only websites, systems, and accounts that you own or have explicit permission to assess. Active requests can affect availability, generate alerts, change data, or trigger third-party defenses, so treat authorization as an operational prerequisite rather than a formality.
Write down what is in scope
- Primary domains and every approved subdomain.
- Public and private APIs, mobile back ends, administration panels, and authentication endpoints.
- Production, staging, development, and any cloud or CDN endpoints that are included.
- Approved test accounts, roles, test data, time windows, source IP addresses, and emergency contacts.
Protect production systems
Prefer a staging copy for intrusive tests. If production must be tested, agree on request limits, excluded actions, monitoring, rollback steps, and a stop condition before you begin. Do not submit destructive forms, create large numbers of accounts, upload malware samples, or attempt denial-of-service activity during a routine check.

Before looking for vulnerabilities, understand how a normal user and an unauthenticated client can reach the application. This inventory determines which tests are relevant and prevents a scanner from becoming your only view of the site.

- Login, registration, password-reset, multifactor, logout, and account-recovery flows.
- Cookies, local storage, security-relevant response headers, and cache behavior.
- Public documentation, JavaScript bundles, source maps, robots files, and other externally exposed assets.
Inventory APIs and roles
List API hosts and versions, HTTP methods, authentication requirements, and the roles that can call each function. Note which requests are available before login and which objects or actions change when a user, tenant, or administrator is selected. Keep the inventory with the date and environment because public routes change.
3. Check HTTPS, certificates, and TLS
Transport checks answer whether visitors can establish a trusted encrypted connection and whether the site consistently uses it. They do not test authorization, business rules, or injection handling.
Verify the certificate
- Open the site using its canonical hostname and confirm the certificate is trusted by current browsers.
- Check that the certificate name covers the hostname, that it is not expired or revoked, and that the chain is complete.
- Repeat the check for every in-scope hostname, including API and administrative hosts.
Check HTTP-to-HTTPS behavior
Request the HTTP version and confirm it redirects to the intended HTTPS URL without exposing sensitive content first. A quick header check from a terminal is:
Recommended Free Tools
curl -I http://example.com
curl -I https://example.comReview the status code, Location value, and whether any alternate hostname or path remains on plain HTTP. Follow the redirect chain for login, account, checkout, and API endpoints rather than checking only the home page.
Review TLS configuration
Use a current TLS assessment tool or server configuration review to check protocol versions, cipher choices, certificate strength, and consistent HTTPS responses. Correct findings in the web server, application server, CDN, load balancer, or reverse proxy that actually terminates TLS; changing only the origin may not change what users receive.
4. Check HSTS and the delivery path
On an HTTPS response, inspect the Strict-Transport-Security header:
curl -sI https://example.com | grep -i strict-transport-securityConfirm the policy reaches users
Check the header on the canonical site, authenticated pages, API hosts, and representative paths. Compare responses at the CDN, load balancer, reverse proxy, and origin when those layers differ. A header added at the origin can be removed or replaced before it reaches a browser.

Understand what HSTS does
A browser learns HSTS after receiving the policy over HTTPS. It then upgrades later HTTP attempts for the covered host to HTTPS. A first-time visitor is not protected by a policy they have never received, and a broken HTTPS deployment can prevent access once a browser has cached the policy.
Treat preload as a separate decision
Do not enable preload casually. Every affected subdomain must be HTTPS-ready, including hosts that are not part of the main website. Submission is an organizational decision because removing a domain from preload can be slow and does not immediately undo every cached policy.
5. Review the application controls
Organize manual checks around the parts of the application that enforce security. The applicable tests depend on the site’s data, roles, integrations, and business requirements.
Configuration and deployment
Look for debug mode, default credentials, exposed administrative consoles, unnecessary services, directory listings, unsafe file permissions, verbose server banners, and secrets in configuration or client-side assets.

Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Identity and authentication
Check account creation, password policy, login throttling, multifactor enrollment and recovery, password reset tokens, session invalidation after password changes, and protections against account enumeration. Test both successful and failed paths with approved accounts.
Authorization
For each role, attempt only the approved, non-destructive variations of an action. Confirm that changing an object identifier, tenant identifier, HTTP method, or client-side control cannot grant access to another user’s data or an administrator-only function.
Session management
Inspect cookie scope and flags, including Secure, HttpOnly, and an appropriate SameSite setting. Check session rotation at login and privilege changes, logout invalidation, idle and absolute timeouts, concurrent-session handling, and protection against cross-site request forgery where state-changing requests rely on cookies.
Input handling and injection
Identify every input boundary and test safely for context-appropriate validation and encoding. Consider SQL, command, template, XML, directory-traversal, server-side request-forgery, cross-site scripting, and header-injection risks where the technology stack makes them relevant. Stop when a test could alter data or reach an external system without an approved procedure.

Error handling and logging
Trigger ordinary validation failures and controlled server errors. Responses should not disclose stack traces, credentials, tokens, internal paths, or database details. Logs should capture security-relevant events with enough context for investigation while avoiding passwords, session secrets, and unnecessary personal data.
Cryptography and sensitive data
Check that sensitive data is encrypted in transit and protected appropriately at rest, that keys are stored separately from application code, and that tokens, password-reset links, and signed values have suitable lifetime, scope, and invalidation behavior.
Business logic
Test the rules that scanners commonly miss: price or quantity changes, duplicate submissions, skipping required workflow steps, replaying one-time actions, race conditions, approval separation, rate limits, and limits on file or resource consumption. Use harmless test records and preserve the approved transaction boundaries.
Client-side behavior
Review browser-executed JavaScript, cross-origin policy, framing protections, content-security policy where deployed, exposed source maps, dangerous DOM sinks, and assumptions that are enforced only in the user interface. Anything enforced only in client code must also be enforced by the server.

6. Use scanners and dependency checks carefully
Automate the repeatable work
OWASP identifies ZAP as a web-scanning resource and Dependency-Check as a dependency-review resource. Configure tools for the authorized environment, limit request rates, exclude destructive actions, and preserve the tool version and settings with the results.
Scan dependencies and exposed services
Review server-side packages, frameworks, container images, libraries, and front-end dependencies against trusted vulnerability information. An internet-facing asset scan can identify exposed services and known weaknesses, while a web-application scan exercises publicly accessible application behavior; the appropriate coverage depends on the asset and the service available in your region.

Treat output as leads
Scanners can miss business logic, authorization flaws, undocumented routes, and vulnerabilities hidden behind authentication. They can also report false positives caused by unusual frameworks or intentional behavior. Reproduce each important finding manually, record the request and response evidence, and determine whether the issue is exploitable in your application.
7. Validate, prioritize, fix, and retest
Keep a finding record that another person can understand without rerunning the entire assessment.
| Record | What to capture |
|---|---|
| Scope | Hostname, environment, route or API, account role, date, and authorization reference. |
| Evidence | Reproduction steps, sanitized requests and responses, screenshots where useful, and tool settings. |
| Impact | Data, users, privileges, or availability that could be affected, plus prerequisites and limits. |
| Disposition | Confirmed, false positive, accepted risk, duplicate, or needs more investigation, with an owner and due date. |
| Fix verification | The changed version or configuration, retest date, and evidence that the weakness no longer reproduces. |
Prioritize confirmed risk
Address issues that permit unauthorized access, expose sensitive information, compromise administrative functions, or affect many users before lower-impact findings. Consider exploit prerequisites, affected assets, monitoring, and available mitigations rather than relying on a scanner severity label alone.
Make checking continuous
After remediation, rerun the original proof and nearby regression checks. Add dependency review, key header checks, and suitable authenticated or unauthenticated scans to the development or deployment workflow. Monitor for new exposed hosts, expired certificates, configuration drift, and changes to authentication or authorization behavior.
8. Choose the right level of assessment
| Approach | Best coverage | Access and expertise | Operational considerations | What it cannot establish alone |
|---|---|---|---|---|
| Manual first-pass check | Transport, headers, routes, forms, roles, and obvious control failures. | Owner or developer with test accounts and application knowledge. | Low cost and adaptable, but requires disciplined notes and safe test data. | Complete coverage of hidden behavior, complex workflows, or every vulnerability class. |
| Automated web and dependency scanning | Repeatable checks for known configuration, exposed technology, dependency, and common web issues. | Tool configuration, authorized target, and someone able to interpret results. | Efficient for regression checks; rate limits and exclusions are essential. | Reliable proof that a reported issue is exploitable or that business logic is correct. |
| Qualified professional assessment | Deeper authenticated testing, complex authorization, business logic, APIs, and coordinated reporting. | Specialist expertise, formal rules of engagement, and access to suitable environments. | Requires scheduling, cooperation, and an incident or stop procedure. | It is still a time-bounded assessment, not a permanent guarantee. |
Use more than one method when the application is important: manual mapping supplies context, automation supplies repeatability, and specialist testing can investigate high-risk or ambiguous behavior.

Escalate to a deeper test plan or qualified professional when the site handles sensitive personal, financial, health, or authentication data; supports multiple tenants or privileged roles; processes valuable transactions; exposes complex APIs; or has findings you cannot safely reproduce or assess. OWASP’s Web Security Testing Guide (WSTG) is a planning reference for broader testing. Its project page lists version 4.2 as available and version 5.0 as in development as of September 30, 2026; technical guidance can change as the project evolves.
OWASP states in its introduction and objectives: “Security testing will never be an exact science where a complete list of all possible issues that should be tested can be defined.” Treat that as a reason to tailor the plan to the application, not as a reason to skip basic checks.
How do I check if my website is secure?
Start with authorization and an asset inventory, then verify certificates, redirects, TLS, and HSTS. Map routes, inputs, cookies, APIs, and authentication flows; test the relevant identity, authorization, session, input, error, cryptographic, business-logic, client-side, and API controls; run controlled automated and dependency scans; validate findings manually; fix them; and retest. The result is evidence about the checks performed, not a claim that every possible weakness has been eliminated.
How do I scan my website for vulnerabilities?
Choose an authorized staging or production target, configure an automated web scanner with safe rate limits and exclusions, run dependency review, save the tool version and settings, and investigate every material result. Use the scan to find leads and repeatable regressions, then supplement it with manual authenticated testing and deeper assessment where the application’s data, roles, or workflows justify it.
