Continuous HTTP headers monitoring (22 checks)

Continuous HTTP headers monitoring is an ongoing (monthly) service: we regularly check your site's responses on an agreed set of URLs and compare up to 22 headers against a baseline we fix together with you. This includes security headers (HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, Cross-Origin-Resource-Policy, Cross-Origin-Opener-Policy and others), caching and delivery headers (Cache-Control, Vary, ETag, Alt-Svc), and reporting headers. If after a deploy or config change a header disappears, weakens (e.g. the CSP starts allowing too much), changes value or stops being served on some pages, you immediately get an alert with details. Honestly about the essence: this is detection of changes and alerting, NOT configuration and NOT fixing — we do not set the headers on your server and do not "make the site secure"; configuration and remediation are done by your team or by us separately. And crucially: a header being present is not the same as a correct configuration, and a correct configuration is not the same as "the site is secure" — headers are only one layer, and monitoring does not guarantee the absence of vulnerabilities or a breach; it catches drift and regressions in the headers. Importantly: we watch drift from a baseline — so a base set of headers must already be in place; if there are none at all, a one-time setup is needed first (separately), and only then continuous monitoring so they do not "drift". Coverage is only the configured URLs; as the site grows the list must be kept current together with you. False positives are possible on legitimate changes (you changed the policy yourself) — so we update the baseline by agreement. Access to the site is needed to check responses; someone must react to an alert. This is a snapshot at each check moment, assembled into a continuous picture. An important boundary: this is ongoing header monitoring, not a one-time security audit (a deep review with recommendations — separate) and not server/CDN setup. If the site is simple, with no forms, accounts or sensitive data, a strict header set and continuous monitoring may be overkill — a one-time check is enough. Picture this: instead of "we set up CSP six months ago, and after a redesign it quietly weakened and nobody noticed" you get an alert on the deploy day that the security policy has changed. The base price starts from 9,000 ₽ per month; it depends on the number of URLs and the check frequency.

• You set up security headers but do not know whether they "drifted" after deploys.
• After a redesign or migration some headers may have silently disappeared.
• You are not sure CSP and other policies have not weakened over time.
• You learn about header problems only from an external check or an incident.

• Comparison of up to 22 headers against a fixed baseline
• Security headers (HSTS, CSP, X-Frame, X-Content-Type, Referrer-Policy, Permissions-Policy, CORP, COOP)
• Caching and delivery headers (Cache-Control, Vary, ETag, Alt-Svc) + reporting
• Alerts on a header disappearing, weakening or changing
• Checking on an agreed set of URLs
• Baseline updates by agreement (fewer false positives)
• Monthly continuous operation of the check
• An alert channel of your choice (email, messenger, webhook)

• You quickly learn if a header disappeared or weakened after a deploy
• You see on which URL and which header changed
• Less chance of silently losing the configured protection over time
• You know what to set or restore (configuration — separately)

• We fix the header baseline, agree on URLs and the alert channel; collect access
• We set up the regular comparison of up to 22 headers against the baseline
• We launch the continuous check and update the baseline on legitimate changes

• Will you set up the headers and make the site secure?

  No. This is monitoring: it compares headers against a baseline and sends an alert on a change. Setting headers on the server, configuring CSP and remediating issues are done by your team or by us separately. And headers being present is not the same as "the site is secure" — it is only one layer, monitoring does not guarantee the absence of vulnerabilities.

• What if my headers are not set at all?

  Then a one-time setup is needed first (separate work or a security audit with recommendations), because monitoring watches drift from a baseline. Once a base set exists, continuous monitoring keeps it from "drifting" over time.

• Is this a subscription or a one-time check?

  An ongoing service with monthly billing: we fix the baseline once, then the comparison runs continuously and sends alerts. A one-time header check is part of a security audit, a different format.
