SECURITY-FIRST ENGINEERING

Security Practices

Every web application we build is fortified with enterprise-grade security — not as an afterthought, but as the foundation. These are the 89 security dimensions our Website Auditor actively scores, and every one of them is engineered into your application from day one.

Audited & Enforced in Every Build

Our proprietary Website Auditor scores every application across these security dimensions before launch. Nothing ships until every check passes.

HTTPS & Encrypted Connections

Every application is served exclusively over HTTPS with TLS 1.3. HTTP requests are automatically redirected via 301 to HTTPS, ensuring every byte of data between your users and your server is encrypted in transit. Mixed content is eliminated — no insecure resources load on secure pages.

HTTPS enforcement with TLS 1.3
HTTP → HTTPS 301 redirect
Mixed content elimination
Secure WebSocket (WSS) connections

HSTS — HTTP Strict Transport Security

We set the Strict-Transport-Security header with max-age=63072000 (2 years), includeSubDomains, and the preload directive — then submit your domain to the browser HSTS preload list (hstspreload.org). Once preloaded, browsers will never attempt an insecure connection to your domain, even on the very first visit.

max-age ≥ 31536000 (1+ years)
includeSubDomains directive
preload directive enabled
hstspreload.org submission

Content Security Policy (CSP)

A strict Content-Security-Policy header defines exactly which sources of scripts, styles, images, fonts, frames, and connections your application will accept. We implement nonce-based policies where feasible to eliminate unsafe-inline directives, achieving CSP strictness scores of 70+ out of 100. This is your first line of defense against Cross-Site Scripting (XSS) and injection attacks.

Nonce-based inline script/style policies
Explicit source lists per directive
unsafe-inline minimized or eliminated
CSP strictness score 70+/100

X-Content-Type-Options

The X-Content-Type-Options: nosniff header is set on every response. This prevents browsers from MIME-sniffing a response away from the declared Content-Type — blocking drive-by download attacks and ensuring scripts are only executed when served with a correct JavaScript MIME type.

nosniff directive on all responses
MIME-type sniffing prevention
Drive-by download attack mitigation

X-Frame-Options — Clickjacking Protection

The X-Frame-Options header prevents your application from being embedded in malicious iframes — blocking clickjacking attacks where an attacker overlays invisible frames to trick users into clicking hidden buttons. We set DENY or SAMEORIGIN depending on your embedding requirements.

DENY or SAMEORIGIN enforcement
Clickjacking attack prevention
frame-ancestors CSP directive backup

Referrer-Policy

We set Referrer-Policy: strict-origin-when-cross-origin to control exactly how much URL information is shared when users navigate away from your site. This prevents sensitive URL parameters (tokens, session IDs, query strings) from leaking to third-party destinations.

strict-origin-when-cross-origin policy
URL parameter leakage prevention
Cross-origin referrer control

Permissions-Policy

The Permissions-Policy header restricts which browser features your application can access — camera, microphone, geolocation, payment, USB, autoplay, and more. We lock down every feature your application doesn't need, shrinking the attack surface and protecting user privacy.

Camera, microphone & geolocation restriction
Payment API access control
USB & autoplay lockdown
5+ browser features restricted

Cross-Origin Policies (COOP / CORP / COEP)

Three complementary headers harden your application against cross-origin attacks: Cross-Origin-Opener-Policy (same-origin-allow-popups) prevents window.opener exploits, Cross-Origin-Resource-Policy controls who can load your resources, and Cross-Origin-Embedder-Policy enforces CORS on all embedded content.

Cross-Origin-Opener-Policy set
Cross-Origin-Resource-Policy set
Cross-Origin-Embedder-Policy set
Window.opener exploit prevention

Server & Technology Obfuscation

We remove or obfuscate the Server and X-Powered-By headers that expose your technology stack to attackers. Knowing you run a specific framework version gives attackers a roadmap of known vulnerabilities. We eliminate that roadmap entirely.

Server header obfuscated
X-Powered-By header removed
Technology fingerprinting prevention

External Link Security

Every external link includes rel="noopener noreferrer" and target="_blank" attributes. This prevents tabnabbing attacks — where a linked page uses window.opener to redirect your original tab to a phishing page — and stops referrer data from leaking to external domains.

rel="noopener noreferrer" on all external links
target="_blank" with security attributes
Tabnabbing attack prevention
Referrer leakage to external sites blocked

Cookie Hardening

All cookies are set with Secure (HTTPS only), HttpOnly (no JavaScript access), and SameSite=Strict or Lax attributes. This triple defense prevents session hijacking via XSS, cross-site request forgery (CSRF), and man-in-the-middle cookie theft.

Secure flag (HTTPS-only cookies)
HttpOnly flag (no JS access)
SameSite=Strict or Lax
Session hijacking & CSRF prevention

Secure Form Actions

Every form in your application submits exclusively to HTTPS endpoints. We audit all form action attributes to ensure no user data — passwords, credit cards, personal information — is ever transmitted over an insecure HTTP connection.

All form actions use HTTPS
No insecure form submissions
User data transmission encryption

Privacy Policy & Cookie Consent

We ensure your application includes a detectable privacy policy link and a cookie consent mechanism — meeting GDPR, CCPA, and ePrivacy directive requirements. Our auditor checks for both elements and flags their absence.

Privacy policy link detection
Cookie consent banner implementation
GDPR & CCPA compliance signals
ePrivacy directive alignment

Subresource Integrity (SRI)

External scripts and stylesheets include integrity hash attributes that verify file contents haven't been tampered with. If a CDN is compromised and serves malicious code, the browser will refuse to execute it — stopping supply-chain attacks before they start.

integrity attributes on external resources
CDN tampering prevention
Supply-chain attack mitigation
Hash verification on load

CSP Depth Analysis & Nonce Policies

Beyond basic CSP, our auditor performs depth analysis — scoring strictness out of 100, counting unsafe-inline directives, verifying nonce-based policies, and ensuring script-src, style-src, img-src, connect-src, and frame-src are all explicitly defined. Modern SSR frameworks require specific CSP accommodations, and we configure them correctly.

CSP strictness scoring (70+/100)
Nonce-based inline protection
Per-directive source lists
SSR framework CSP compatibility

Rate Limiting & DDoS Protection

Form endpoints and API routes are protected with rate limiting headers that throttle excessive requests — preventing brute-force login attacks, form spam, and application-layer DDoS. We configure intelligent rate limits that protect without impacting legitimate users.

Rate limit headers on API endpoints
Brute-force attack prevention
Form spam throttling
Application-layer DDoS mitigation

Dependency & Library Security

We audit all JavaScript libraries for known CVEs (Common Vulnerabilities and Exposures) and flag outdated versions. jQuery, Bootstrap, Lodash, Moment.js — any library with a published vulnerability is updated or replaced before your application launches.

Outdated library detection
Known CVE scanning
Automated dependency updates
Supply-chain vulnerability monitoring

OWASP Top 10 Coverage

Every application is engineered against the OWASP Top 10 — the industry-standard classification of the most critical web application security risks: Injection, Broken Authentication, Sensitive Data Exposure, XML External Entities, Broken Access Control, Security Misconfiguration, XSS, Insecure Deserialization, Insufficient Logging, and Server-Side Request Forgery.
