Website, Application & AI Cyber Security
We secure the websites, online stores and SaaS apps we build and run, and we can do the same for yours: Cloudflare in front, the server locked down, software patched, and the gaps in caching and logins closed.
Practical hardening by the engineers who build the software, for businesses in India and the USA.
- WordPress & WooCommerce
- Cloudflare WAF & DDoS protection
- Server hardening
- Security headers & HTTPS
- Patching & monitoring
- Backups you can restore
What we do
Security check-up
We look at your site the way an attacker would: open login and admin pages, exposed backup and config files, missing security headers, old PHP or plugins, and your DNS and email records (SPF, DKIM, DMARC). You get a plain fix list, highest risk first.
Cloudflare setup and firewall
We move your DNS to Cloudflare without downtime and turn on full HTTPS, firewall rules, bot and DDoS protection, plus caching rules that never cache logins, carts or checkouts.
Server lock-down
Your server answers only Cloudflare, SSH works by key only, and the firewall and web server are set up for your app, not left on defaults.
WordPress & WooCommerce hardening
Plugin clean-up, PHP and core updates tested on staging first, login protection, and the hosting firewall tuned so it blocks attacks but not your editors.
Patching and monitoring
Monthly updates for PHP, frameworks and plugins, fast patches when a serious flaw is announced, and alerts when the site goes down or starts throwing errors.
Backups and recovery
Daily backups kept off the server, a retention rule so they don't pile up, and a tested restore, so a bad day stays short.
Application and AI security
For web apps, SaaS products and AI agents we check logins, roles and access control, API keys and secrets, input validation, and what data an AI agent can read or send. AI agents get the least access they need, keys stay out of the code, and every tool an agent can call is logged.
From our recent work
A cache rule that broke Google sign-in
On a US software store, about 63 of 108 Google sign-in attempts over three weeks were answered from Cloudflare's cache and failed without an error. We traced it in Cloudflare's analytics, fixed the rule the same day and confirmed sign-in works.
Homepage serving the wrong page
On the same store, one crawler visit made Cloudflare cache a redirect on the homepage for 46 minutes. We found the cause in the cache key and changed the rule so it cannot happen again.
Two SaaS apps moved behind Cloudflare
An e-signature app and a document app went from a bare server to Cloudflare with full HTTPS and security rules, and the servers now answer only Cloudflare.
Next-day patch for a critical PHP flaw
When remote-code-execution flaws in PHP were announced in October 2026, the store was running the fixed PHP release the next day.
A firewall that blocks attackers, not editors
We reviewed 3,499 firewall blocks. None hit real Google or Bing crawlers or shoppers; the "AI bot" hits were fake bots hunting for secret files. One rule that stopped editors from saving posts was found and switched off on its own.
What we don't do
We are engineers, not a certified security lab. For a formal penetration test or a compliance certificate (ISO 27001, SOC 2, PCI DSS), work with an accredited auditor. We get your site ready for the audit and fix what they find.
How it works
1. Free outside check
Send us your website address. We check it from the outside (HTTPS, headers, exposed files, DNS and email records) and reply with the top risks.
2. Fix plan
A short list of fixes with a fixed price, highest risk first.
3. Fix
We make the changes on staging first where possible, then live, and show you the before and after.
4. Keep it safe
Optional monthly patching, monitoring and backup checks.
Questions
Will moving to Cloudflare take my site down?
Done right, no. We copy every DNS record first, check email, payment webhooks and logins, and switch the nameservers at a quiet hour.
Do you work on sites you didn't build?
Yes. WordPress, WooCommerce, Laravel, PHP and Node.js sites on shared hosting, managed WordPress hosts and cloud servers.
Do you do penetration testing?
Not as a certified tester. We do hardening and configuration reviews, and we fix what a penetration test or audit finds.
What does it cost?
A fixed price for the check-up and the setup, and a monthly fee if you want us to keep patching and watching. Tell us about your site and we will quote.
