Cloudflare Zero Trust & Starlink CGNAT Home Network – Project Summary This project involves designing a secure home SASE-style network using Starlink Gen 3 (CGNAT) and Cloudflare Zero Trust to protect internal infrastructure while enabling secure remote access. Because Starlink operates behind CGNAT, traditional port forwarding cannot be used. Instead, Cloudflare Tunnel will create encrypted outbound connections to securely expose internal services without opening inbound ports. The network includes NAS storage, Home Assistant, IoT devices, PTZ/NVR security cameras, UPS monitoring systems, and smart-home integrations (Google Home, Alexa, Apple Home). The architecture must provide secure remote administration while maintaining normal automation functionality. Security will rely...

My website has suddenly started throwing the message, “Error: Server Error – The service you requested is not available yet. Please try again in 30 seconds.” The outage appeared only recently and was not preceded by any obvious code or configuration changes on my side. I need someone to trace the root cause and restore normal operation. You’ll be working directly on the live site, so a careful, backup-first approach is essential. Once you locate the issue—whether it points to a misconfigured server, an unhandled 500-level condition, or a resource-limit problem—I expect a clear explanation of what happened and the corrective steps you took. Deliverables: • Diagnosis report outlining the exact failure point • Implementation of the fix and con...

My phone and Mac-based computer were recently compromised and I am seeing clear signs of unauthorized access, suspicious background activity, and some missing files. I need an experienced ethical hacker or cybersecurity specialist who can remotely examine both devices, identify every backdoor or malicious profile, recover any lost data where possible, and lock everything back down so I am fully in control again. Your work will involve a forensic sweep of macOS (and the companion phone, likely iOS) to trace how the intruder got in, remove any malware or configuration profiles they left behind, and then hard-harden the system—ensuring strong authentication, updated firmware, and airtight network settings. Please be comfortable using common incident-response tooling such as Wireshark, ...

My site is suddenly being flagged with a phishing warning and visitors see a “risky site” message. I haven’t touched the code or added new pages in quite some time, so I need a fresh set of expert eyes to uncover what’s triggering the alert and to get the flag removed. Small task, couple of hours research by someone with the right skills. Current situation • Phishing warning appears on major browsers and link-sharing platforms. • No recent content or code updates on my end. • The site does rely on a few third-party plugins/integrations that could be a vector. What I’m after I want a concise security assessment that pinpoints the root cause—whether it’s injected scripts, compromised plugin files, mixed-content issues, or so...

My site already runs through Cloudflare and basic protection is in place, yet I know the platform can do much more for security. I want a seasoned Cloudflare specialist to go through my current setup, tighten every loose end, and leave me with a hardened configuration I can trust. Scope of work • Firewall rules – Review what I have, remove redundancies, and add precise allow/deny rules and rate limits that match real-world traffic patterns without blocking legitimate users. • SSL/TLS – Move the zone to the most secure Full (Strict) mode, renew or generate any required origin certificates, enforce HSTS and secure ciphers, and confirm end-to-end encryption is flawless. • Bot management – Configure Bot Fight Mode and related features so genuine traffic ...

I need Cloudflare configured so my site automatically blocks malicious or nuisance traffic rather than legitimate visitors. The immediate headache is spam-driven form submissions and crawlers hammering the same pages hundreds of times a minute, so the goal is to stop those two behaviours without slowing genuine users. I already have a Cloudflare account in place; what I’m missing are the right firewall rules, bot management settings, and rate-limiting thresholds. You’ll review my current WAF/Bot Management setup, identify the loopholes that allow automated form posts and excessive page requests, then implement Cloudflare features such as Bot Fight Mode, custom WAF rules, Challenge or Turnstile for forms, and sensible request limits. Deliverables • Documented list of ...

I need a thorough, professional penetration test that zeroes in on database security. The work will involve actively probing our live environment for misconfigurations, permission-escalation paths, injection points, improper encryption, and any other weakness that a determined attacker might exploit. Scope • Assess the entire database layer—from connection strings and authentication flows to stored procedures and backup endpoints—without disrupting business operations. • Document every finding with reproducible steps, risk ratings, and clear remediation guidance. • Validate fixes with a follow-up retest so we can close the loop confidently. Deliverables 1. Methodology outline (tools, test phases, compliance references). 2. Vulnerability assessment...

My personal blog runs on a standard LAMP stack and I want a clear, ethical snapshot of its current security posture. The focus is on preventing data breaches and blocking any avenue for unauthorized access; malware checks are welcome but secondary. Scope You will carry out a legally authorised vulnerability assessment that covers: • A surface scan of the domain and sub-domains, mapping open ports and exposed services. • Manual and automated testing against the OWASP Top 10, using tools such as Burp Suite Community/Pro, OWASP ZAP, Nikto, or similar. • SSL/TLS configuration review, confirming protocol versions, cipher strength, and certificate chain integrity. • Inspection of server and application misconfigurations that could lead to privilege escalation, credenti...
