Full coverage: every applicable check was assessed.
What to do first
- 1.
Turn on DNS signing for your domain
Signing helps resolvers detect forged answers about your domain.
Who can fix it: Your domain registrar or DNS provider
How to verify after the fix
dig +short DS intercom.com
- 2.
Choose which companies may issue certificates for your domain
This reduces the chance of a certificate being issued by a provider you did not choose.

Live TLS handshake succeeded. Latest issuance in CT logs: Amazon Trust Services, expiring 2027-05-02 (168 days). CT shows issued certificates, not necessarily the one served — confirm dates with the verify command.

CSP — protection from script injection
Needs attention · Severity: Low · Hardening gap · 5/8A script policy exists, but it's permissive and offers only partial protection.
script-src includes: 'unsafe-inline', 'unsafe-eval' — weakens XSS protection.

$ curl -sIL https://intercom.com/ | grep -i "Content-Security-Policy"
- First publish Content-Security-Policy-Report-Only — it blocks nothing, it only reports.
- Collect violations for a week or two and tune the policy to your legitimate sources.
- Switch to the Content-Security-Policy header and replace 'unsafe-inline' with a nonce or hash.
/* Content-Security-Policy-Report-Only: default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'
Safety: This change is made in your server/CDN settings. Test on staging before production. An overly strict CSP will break scripts — that's why you start in Report-Only mode.
Clickjacking protection
Passed · Severity: OK · 5/5The site can't be embedded by foreign sites.
frame-ancestors 'self' *.intercom.com fin.ai *.fin.ai https://app.contentful.com https://*.sanity.studio https://www.sanity.io

$ curl -sIL https://intercom.com/ | grep -i "X-Frame-Options"
X-Content-Type-Options
Failed · Severity: Low · Hardening gap · 0/4The browser may interpret files as code unintentionally.
Missing X-Content-Type-Options: nosniff header (MIME sniffing).
X-Content-Type-Options: (missing)
$ curl -sIL https://intercom.com/ | grep -i "X-Content-Type-Options"
- Add X-Content-Type-Options: nosniff to every response.
/* X-Content-Type-Options: nosniff
Safety: This change is made in your server/CDN settings. Test on staging before production.
Referrer-Policy
Failed · Severity: Low · Hardening gap · 0/3Internal URLs (including parameters) may leak to external sites.
Referrer-Policy is missing; the browser will use its default.
Referrer-Policy: (missing)
$ curl -sIL https://intercom.com/ | grep -i "Referrer-Policy"
- Set Referrer-Policy: strict-origin-when-cross-origin.
/* Referrer-Policy: strict-origin-when-cross-origin
Safety: This change is made in your server/CDN settings. Test on staging before production.
Permissions-Policy
Needs attention · Severity: Low · Hardening gap · 0/2Access to sensitive features like the camera and location isn't restricted.
Missing Permissions-Policy header.
Permissions-Policy: (missing)
$ curl -sIL https://intercom.com/ | grep -i "Permissions-Policy"
- Disable browser features the site doesn't need (camera, microphone, geolocation).
/* Permissions-Policy: camera=(), microphone=(), geolocation=()
Safety: This change is made in your server/CDN settings. Test on staging before production. Don't disable a feature the site actually uses.
Software version disclosure
Passed · Severity: OK · unscoredThe server doesn't disclose software versions.
No version numbers found in the Server / X-Powered-By headers.
server: cloudflare x-powered-by: Next.js
$ curl -sIL https://intercom.com/ | grep -iE "^(server|x-powered-by)"
DNSSEC — signed DNS records
Needs attention · Severity: Medium · Hardening gap · 0/7The domain's records aren't signed, so in some scenarios users could be redirected to a forged server.
No DS record is published at the parent zone, so there's no DNSSEC chain of trust for this zone.
AD = false DS intercom.com: NODATA
$ dig +short DS intercom.com
- Enable DNSSEC at your DNS provider (one click at most providers).
- Copy the DS record your provider generates to your domain registrar.
- Wait for propagation and verify with DNSViz.
dig +dnssec intercom.com SOA delv intercom.com
Safety: DNS changes are made only at your DNS provider. This tool only reads public data and changes nothing on the domain. A wrong DS record at the registrar will make the domain stop resolving — copy it exactly from the provider.
CAA — who may issue certificates
Needs attention · Severity: Low · Hardening gap · 0/5Any certificate authority can issue a certificate for the domain, raising the risk of mis-issuance.
No CAA records found. RFC 8659 lets the domain owner restrict which CAs are authorized.
(no CAA records found)
$ dig +short CAA intercom.com
- Identify which certificate authority issued your current certificate (see the certificate check).
- Publish CAA for that authority only, and add iodef to receive alerts.
intercom.com. CAA 0 issue "letsencrypt.org" intercom.com. CAA 0 iodef "mailto:security@intercom.com"
Safety: DNS changes are made only at your DNS provider. This tool only reads public data and changes nothing on the domain. If your CDN issues certificates on your behalf, include it too — otherwise certificate renewal will fail.
DNS server redundancy
Passed · Severity: OK · 3/3The domain is served by several DNS servers, so one server failing won't take it down.
4 NS servers.

Indicative alignment
Best-practice mapping of public findings to common frameworks. Passive scanning tests public configuration only; it doesn't prove compliance or a violation.
- Google & Yahoo sender rulesNo gaps observed
- PCI DSS v4.01 observed gaps
- NIS2 / vendor due diligence2 observed gaps
- SOC 2 / ISO 27001 baseline2 observed gaps
Indicative alignment only, based on public configuration. It doesn't establish whether a framework applies to you, and it isn't legal advice, an audit or a certification.
