CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis.
default-src 'self'Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Content-Security-Policy is the browser-enforced firewall against XSS. With a strict CSP, a script injection that would otherwise steal session cookies or rewrite the page is silently blocked. Without it, your only defense is hoping every input on every form is escaped correctly forever.

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.

Submit your domain to hstspreload.org to close the trust-on-first-use gap. Requires a preload-ready HSTS header (max-age=31536000+, includeSubDomains, preload).
Not in the Chrome preload list — first-time visitors over plain HTTP can be downgraded by a network attacker before HSTS kicks in.
Learn more ▾ ▴
The HSTS header only protects users who have already visited the site (TOFU window). Adding your domain to the Chrome preload list closes that gap so HSTS is enforced from the very first connection. Requires a preload-ready header (max-age=31536000+, includeSubDomains, preload) then submission at hstspreload.org. Inclusion ships in the next Chrome release after acceptance.

CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading.

Content-Security-Policy is the browser-enforced firewall against XSS. With a strict CSP, a script injection that would otherwise steal session cookies is silently blocked. Without it, your only defense is hoping every input on every form is escaped correctly forever. Start in Report-Only mode, fix violations, then graduate to enforcing.

FEmail SecurityActionno DMARC, no SPFFIX
No DMARC record found
Without DMARC, email receivers have no policy for handling authentication failures from your domain.
Without DMARC, email receivers have no policy for handling authentication failures. Add a TXT record at _dmarc.<domain> starting with v=DMARC1.
Without DMARC, anyone can send phishing emails using your domain name.
Learn more ▾ ▴
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.
Source: DMARC.org / NIST
Without SPF (Sender Policy Framework), receivers can't tell which servers are authorized to send mail for your domain. Add a TXT record at the apex starting with v=spf1, ending in -all.
Security gaps expose your site and users to attacks, eroding trust.
DKIM signs outbound mail to prove origin. We probed common selectors (default, google, selector1, etc.) without finding a record. If you use a non-standard selector, this is a false negative.
No DKIM signature on outbound mail — receivers can't cryptographically prove the message came from your domain.
Learn more ▾ ▴
DKIM signs outbound mail with a private key whose public half lives in DNS at <selector>._domainkey.<domain>. Without DKIM, DMARC alone can't tell legitimate mail from spoofs, and large mailbox providers (Gmail, Yahoo) increasingly require DKIM for inbox placement. Note: this check probes a curated list of common selectors; non-standard selectors produce a false negative.

MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts.<domain> and a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt.
Without MTA-STS, inbound mail can be silently downgraded to plain SMTP by a network attacker.
Learn more ▾ ▴
MTA-STS (RFC 8461) tells sending mail servers to use TLS and to refuse delivery if TLS fails. Requires both a TXT record at _mta-sts.<domain> AND a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt. Without it, an active attacker on the network path can strip STARTTLS and read the email in plaintext.
Source: RFC 8461
TLS-RPT (RFC 8460) lets MTAs report TLS-handshake failures, so you can detect and fix MTA-STS misconfigurations. Add a TXT record at _smtp._tls.<domain>.
Without TLS-RPT, you have no visibility into inbound TLS failures — MTA-STS misconfigurations stay hidden until users complain.
Learn more ▾ ▴
TLS-RPT (RFC 8460) is the feedback channel for MTA-STS: senders post aggregate reports of TLS-handshake failures to the URI in your _smtp._tls TXT record. Without it, an MTA-STS misconfiguration silently rejects mail and you find out only when someone notices missing email.
Source: RFC 8460
BIMI (Brand Indicators for Message Identification) lets supporting clients (Gmail, Apple Mail, Yahoo) display your verified logo next to your messages. Optional but raises trust signals. Requires DMARC at p=quarantine or p=reject to be honored.
Security gaps expose your site and users to attacks, eroding trust.

Known Vulnerabilities
| Library | Version | Severity | Summary | Fixed In |
|---|---|---|---|---|
| Handlebars | 4.0.12 | high | A prototype pollution vulnerability in handlebars is exploitable if an attacker can control the template | 4.0.13 |
| Handlebars | 4.0.12 | high | Versions of `handlebars` prior to 3.0.8 or 4.5.2 are vulnerable to Arbitrary Code Execution. The package's lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript in the system. It can be used to run arbitrary code in a server processing Handlebars templates or on a victim's browser (effectively serving as Cross-Site Scripting). The following template can be used to demonstrate the vulnerability: ```{{#with "constructor"}} {{#with split as |a|}} {{pop (push "alert('Vulnerable Handlebars JS');")}} {{#with (concat (lookup join (slice 0 1)))}} {{#each (slice 2 3)}} {{#with (apply 0 a)}} {{.}} {{/with}} {{/each}} {{/with}} {{/with}} {{/with}}``` ## Recommendation Upgrade to version 3.0.8, 4.5.2 or later. | 4.5.2 |
| Handlebars | 4.0.12 | high | Prototype pollution | 4.5.3 |
| Handlebars | 4.0.12 | high | Versions of `handlebars` prior to 3.0.8 or 4.5.3 are vulnerable to Arbitrary Code Execution. The package's lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript in the system. It is due to an incomplete fix for a [previous issue](https://www.npmjs.com/advisories/1316). This vulnerability can be used to run arbitrary code in a server processing Handlebars templates or on a victim's browser (effectively serving as Cross-Site Scripting) | 4.5.3 |
| Handlebars | 4.0.12 | high | Disallow calling helperMissing and blockHelperMissing directly | 4.3.0 |
| Handlebars | 4.0.12 | high | Handlebars before 3.0.8 and 4.x before 4.5.3 is vulnerable to Arbitrary Code Execution. The lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript. This can be used to run arbitrary code on a server processing Handlebars templates or in a victim's browser (effectively serving as XSS). | 4.5.3 |
| Handlebars | 4.0.12 | high | Regular Expression Denial of Service in Handlebars | 4.4.5 |
| Handlebars | 4.0.12 | high | Remote code execution in handlebars when compiling templates | 4.7.7 |
| Handlebars | 4.0.12 | high | Prototype Pollution in handlebars | 4.7.7 |
| Handlebars | 4.0.12 | medium | Affected versions of `handlebars` are vulnerable to Denial of Service. The package's parser may be forced into an endless loop while processing specially-crafted templates. This may allow attackers to exhaust system resources leading to Denial of Service. ## Recommendation Upgrade to version 4.4.5 or later. | 4.4.5 |
| Handlebars | 4.0.12 | medium | Denial of service | 4.6.0 |
| jQuery | 3.4.1 | medium | Regex in its jQuery.htmlPrefilter sometimes may introduce XSS | 3.5.0 |
| jQuery | 3.4.1 | medium | passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. | 3.5.0 |

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.
