Without includeSubDomains, subdomains can still be accessed over HTTP.
max-age=31536000; includeSubDomainsWithout includeSubDomains, a forgotten dev subdomain over HTTP can set malicious cookies that ride to the apex.
Learn more ▾ ▴
HSTS without includeSubDomains protects only the exact domain. Cookies set on a non-HSTS subdomain can ride to the apex via cookie-scope attacks. The fix is one directive append. Verify all subdomains support HTTPS first — adding includeSubDomains to a domain with HTTP-only subdomains breaks them.

This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN.
DENYWithout frame protection, your site can be embedded in a hostile page and used for clickjacking.
Learn more ▾ ▴
Clickjacking overlays your site under a transparent malicious page so users click invisible buttons. Setting X-Frame-Options: DENY (or a modern frame-ancestors CSP directive) blocks the embedding entirely. There's almost never a legitimate reason to allow it.

Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter.
strict-origin-when-cross-originDefault browser behavior leaks full URLs (including query params and tokens) to every third-party resource — set a strict policy.
Learn more ▾ ▴
Without a Referrer-Policy header, browsers send the full referring URL with images, scripts, and fonts loaded from third-party origins. URLs containing tokens, user IDs, or session params end up in third-party logs. Set `Referrer-Policy: strict-origin-when-cross-origin` (or stricter) to limit leakage.

Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
geolocation=(), camera=(), microphone=()Permissions-Policy locks down browser APIs you don't use — without it, every page can request camera/mic/geolocation if XSS lands.
Learn more ▾ ▴
By default every page can request the camera, microphone, geolocation, payment APIs, and dozens more. Permissions-Policy turns off the ones you don't need so a future bug can't quietly start using them. It's a defense-in-depth header — one line, big surface reduction.

COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.
same-originCOOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.
Learn more ▾ ▴
Cross-Origin-Opener-Policy: same-origin prevents cross-origin pages from sharing a browsing-context group with yours. This blocks cross-window references that enable Spectre-style timing attacks and tab-nabbing. Required if you want to enable SharedArrayBuffer.
Source: MDN / web.dev
COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
require-corpCOEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.
Learn more ▾ ▴
Cross-Origin-Embedder-Policy: require-corp ensures every embedded resource (script, iframe, image) explicitly allows being loaded cross-origin. Combined with COOP, this enables the cross-origin-isolated context that unlocks SharedArrayBuffer, high-resolution timers, and other powerful APIs.

DContent Security PolicyAction4 of 10 CSP checks passedFIX
'unsafe-eval' allows eval() and similar functions, enabling code injection. Remove it.
Unsafe value (unsafe-inline, unsafe-eval) in script-src defeats CSP's main protection — XSS injections can execute again.
Learn more ▾ ▴
unsafe-inline allows inline <script> tags; unsafe-eval allows eval() and similar. Both are necessary for some legacy code but explicitly dangerous. Migrate to nonces (per-page random tokens) or hashes (per-script SHA-256) instead.

default-src provides a fallback for other directives. Set it to restrict default resource loading.
default-src 'self'Security gaps expose your site and users to attacks, eroding trust.
Without base-uri, attackers can inject a <base> tag to hijack relative URLs. Set it to 'self' or 'none'.
base-uri 'self'Missing base-uri in CSP leaves a base-tag injection attack path open even on otherwise strict policies.
Learn more ▾ ▴
A common omission: developers add CSP for script-src and frame-ancestors but forget base-uri. The result is a CSP that looks strict but lets an attacker rewrite every URL on the page via <base href>. Add `base-uri 'self'` to close the gap.
Source: MDN CSP
form-action restricts where forms can submit data, preventing form hijacking.
form-action 'self'Security gaps expose your site and users to attacks, eroding trust.
This directive upgrades HTTP resources to HTTPS automatically, preventing mixed content.
upgrade-insecure-requestsWithout upgrade-insecure-requests, any HTTP subresource link survives as a mixed-content warning instead of auto-upgrading.
Learn more ▾ ▴
Adding `upgrade-insecure-requests` to your CSP turns every http:// subresource fetch into https:// at the browser layer. One-line defense against accidental mixed content from legacy links or third-party widgets.

Without DMARC, email receivers have no policy for handling authentication failures.
Without DMARC, anyone can send phishing emails using your domain name.

DMARC tells receiving mail servers what to do with email that fails SPF/DKIM checks for your domain. With a strict 'p=reject' policy, spoofed emails get bounced; without it they reach the inbox. Domains used in phishing campaigns lose deliverability and brand trust fast.

Renew the certificate before it expires to avoid browser warnings.
Cert expiry within the renewal window — fix now while there's no user impact, instead of after expiry when there's a full outage.

Most CAs recommend renewal at 30 days remaining. Inside that window, schedule the renewal immediately and verify auto-renewal is configured if applicable. Don't wait until 7 days; weekend / holiday timing can leave you exposed.

HTTP/2 provides multiplexing and header compression for better performance.
HTTP/1.1 forces the browser to make sequential requests, multiplying latency on every page.
Learn more ▾ ▴
HTTP/2 (and HTTP/3) multiplex many requests over a single connection, eliminating head-of-line blocking. HTTP/1.1 forces the browser to either queue requests or open many parallel connections — both worse. Most modern web servers support HTTP/2 with one config line.
