Web Security & Accessibility Services


CEO-level Web Security & Accessibility services to protect your web applications and ensure compliance. Start with our free WebChecker tool to identify security gaps instantly.

Start here: Free WebChecker

Use our in-house WebChecker to identify missing or misconfigured HTTP security headers, evaluate Content Security Policy (CSP) against best-practice guidance, and export issues for triage.

Our Web Security Services

Security Header Remediation & CSP Hardening

Outline: We fix findings from WebChecker: HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and a tailored CSP (including nonce/hash strategy) without breaking your site.

Benefits: Rapid risk reduction; mitigates clickjacking, MIME sniffing, data leakage and XSS vectors; future-proofs for new features with a change pattern you can reuse.

Outcomes: No critical header gaps; stable CSP with monitored report-only rollout; measurable uplift in third-party header grades.

TLS/HTTPS Modernisation & HSTS

Outline: Upgrade protocols and ciphers, enforce HSTS with safe preload strategy, correct certificate chains, OCSP and SCT where applicable.

Benefits: Strong transport security and better browser trust signals with minimal performance impact.

Outcomes: Modern TLS posture; HSTS safely enforced; reduced mixed-content and downgrade risks.

Web Application Vulnerability Assessment (OWASP-aligned)

Outline: Targeted assessment of your public web apps for OWASP Top 10 categories, business-logic flaws, and misconfigurations. Prioritised fix plan and retest included.

Benefits: Identifies real-world exploit paths before attackers do; gives developers precise, reproducible steps to fix.

Outcomes: Risk-ranked report, developer tickets ready for backlog, and "fixed & verified" evidence per issue.

Secure Platform & CMS Hardening

Outline: Baseline and harden the web stack (server, reverse proxy/CDN, CMS/plugins, file permissions, logging). Introduce least-privilege service accounts and secrets handling.

Benefits: Fewer attack surfaces; lower chance of plugin/RCE incidents; cleaner audit trail.

Outcomes: Documented hardening standard; applied configuration PRs and rollback plan; variance report for audit.

Third-Party Scripts & Supply-Chain Governance

Outline: Inventory all external scripts, tag managers and pixels; set CSP with allowed sources, subresource integrity (SRI) where practical, and change-control for new tags.

Benefits: Cuts XSS/Skimmer risk from third parties; keeps marketing agile without compromising security.

Outcomes: Approved sources list; CSP & SRI in place; monthly drift report and alerting.

Authentication & Session Security

Outline: Review and strengthen login flows (MFA readiness, SSO/OIDC), cookie flags, session lifetimes, CSRF tokens, and forgotten-password pathways.

Benefits: Reduces account takeover risk; smoother user experience with modern identity patterns.

Outcomes: Hardened session cookies; CSRF/XSS protections validated; SSO integration plan (where applicable).

WAF & Bot Mitigation: Implementation & Tuning

Outline: Deploy and tune a Web Application Firewall (WAF) and bot controls (rate-limiting, behavioural rules, challenge policies) with low false positives.

Benefits: Shields apps while fixes roll out; throttles abuse, scraping and credential stuffing.

Outcomes: WAF in blocking mode for critical rules; measurable drop in malicious requests; runbook for tuning.

Continuous Vulnerability Management & Monitoring

Outline: Scheduled scanning (including header/CSP checks from WebChecker), change detection, and ticketed remediation workflow with SLAs.

Benefits: Prevents regression; keeps posture strong across releases; directors gain clear risk trendlines.

Outcomes: Monthly risk scorecard; zero criticals breaching SLA; verifiable retest evidence.

Accessibility Audit & Remediation (WCAG 2.2 AA)

Outline: Hybrid automated and expert audit across templates and key user journeys; fix plan for semantics, keyboard support, colour contrast, focus order, ARIA, forms, media and error messaging.

Benefits: Inclusive experiences, improved usability for everyone, reduced legal/compliance risk.

Outcomes: WCAG 2.2 AA conformance report; remediated components; accessibility statement and governance pattern.

Privacy, Cookies & Consent (UK GDPR/PECR)

Outline: Map data flows, right-size consent experience, implement server-side tagging where suitable, and align cookie categories with security controls and analytics needs.

Benefits: Compliant analytics and marketing while protecting user privacy; fewer blockers from legal.

Outcomes: Lawful-basis register; consent banner tuned to your stack; DPIA template and records of processing.

Incident Readiness & Response for Web Apps

Outline: Playbooks for defacement, data leakage, account compromise and API abuse; tabletop exercises; on-call escalation and comms templates.

Benefits: Faster, calmer responses that preserve evidence and trust.

Outcomes: Practised responders; post-incident review pack; time-to-contain metrics improved.

Developer & Content Team Enablement (DevSecOps Lite)

Outline: Practical coaching: secure patterns for forms, file uploads, templating, CSP nonces, dependency hygiene; CMS/editor guardrails and pre-publish checks.

Benefits: Fewer defects shipped; security integrated into delivery without slowing teams.

Outcomes: Secure coding guides; CI checks added; reduction in recurring categories of issues.
