    My site is already live and collecting customer information, but the current safeguards are minimal. I need an experienced cybersecurity professional to focus exclusively on data protection: assessing the way customer details are stored and transmitted, closing any gaps you identify, and putting long-term controls in place so the data stays safe even as the site scales. What I expect • A concise risk assessment of my existing environment (server, database, APIs, third-party plugins). • Implementation of best-practice controls—end-to-end encryption (SSL/TLS), database hardening, access-control policies, secure backups, and monitoring or alerting tools you feel are essential. • A short validation report or penetration test summary confirming the fixes are effectiv...

    My Shopify store needs a thorough tune-up. I’m looking for someone who can run a complete security and performance audit, then tackle the specific problems I’m facing: • Security: I’m worried about virus or malware infections, possible unauthorized access and any avenue for data breaches. I want the store scanned, cleaned and hardened without disrupting day-to-day trading. • Performance: page-speed has dipped; I’d like clear recommendations and the quick-win fixes implemented. • Metafield cleanup: there are piles of legacy metafields from old apps. Please identify what’s safe to delete and tidy them up so the theme and admin stay lean. • Theme maintenance: several theme sections throw “block reference” errors after a rece...

    I have a complete code-base that now needs to live on a cloud server. The immediate goal is twofold: 1) install and configure the application so it runs reliably in the cloud environment I provide, and 2) comb through every file, dependency, and configuration to confirm there are no hidden backdoors, malicious packages, or insecure default settings left behind after development. I’m deploying to a cloud server (provider is flexible, so please be comfortable with AWS, Azure, or GCP). You’ll set up the runtime stack, handle environment variables, connect the database, and push the first production build. While doing so, perform a thorough security audit: manual inspection, automated scanners, and any static-code-analysis tools you trust. If something suspicious appears, docu...

    I’m creating a crypto-security platform whose very first product is an encrypted wallet-protection service. The site has to look trustworthy, load fast, and, above all, demonstrate that every private key a user stores or transacts with is handled under strong, modern encryption. From the landing page through to the user dashboard, the experience should make it clear that security is the core value we deliver. Here’s what I need built: • A responsive public site that briefly explains how our wallet protection works and why encryption is central to it. • A secure registration and login flow that leads users to their personal dashboard. • Server-side modules that encrypt all sensitive data both in transit and at rest (AES-256 or equivalent), plus an API lay...

    I need ReCAPTCHA v3 added to my login page immediately to stop the persistent spam attacks we have been seeing. The Google console keys are ready, the codebase is clean, and I can give you SSH or admin access the moment we start.

    I want a seasoned penetration tester to put my PHP site through its paces and uncover every weakness, from classic SQL Injection and XSS to more sophisticated remote-code tricks.

Your job is to simulate real-world attacks with tools of your choice (Burp Suite, OWASP ZAP, manual source review, custom exploit scripts—whatever gets the most reliable results) and then document each vulnerability with a clear proof-of-concept, reproducible steps, severity rating, and a practical fix I can hand straight to my developer.
