I want a thorough penetration test against my organisation’s external-facing infrastructure with the sole objective of uncovering every exploitable vulnerability before anyone else does. The scope is limited to the public IP ranges and cloud assets I will provide; nothing on the internal network is in play this time. You are free to use the standard toolkit—Nmap, Nessus, Burp Suite, Metasploit, custom scripts—so long as the testing remains non-disruptive and fully documented. OWASP and PTES methodology are both acceptable; feel free to blend them if it yields deeper coverage. Deliverables I need: • An executive-level summary that highlights critical findings in plain language. • A detailed technical report listing each vulnerability, proof-of-concept evide...

I am conducting an authorised security assessment on a website that currently sits behind Cloudflare. The owner has given me written permission to verify how well the service hides the origin server, and my first objective is simple: locate the true, routable IP address of that server. What I need from you • Discover the origin IP without disrupting production traffic or triggering any Cloudflare security events. • Confirm that browsing directly to the uncovered IP renders the site identically to the public domain (same content, layout, and functionality). • Provide a concise report describing the exact approach—whether you relied on passive DNS enumeration (dig, SecurityTrails, Shodan etc.), historical records, sub-domain leakage, server misconfiguration, or ...

I’m preparing to replace our legacy MPLS links with the SD-WAN service we’ve already contracted and need an on-site engineer in Hyderabad, Telangana to drive the entire cut-over. The environment is small—fewer than 50 routers, switches, firewalls, and edge devices—but the migration still has to be planned and executed with zero-downtime goals. Here’s what I expect: • Audit the current MPLS topology and document every dependency. • Translate existing QoS, security and routing policies into the new SD-WAN orchestrator. • Build and stage configs on the vendor-supplied edge appliances. • Coordinate with our carrier and internal teams to schedule and perform the live switchover. • Validate traffic flow, fail-over behavior, and app...

I need a seasoned PHP security specialist to comb through an existing application, locate and remove every hidden backdoor, then harden the code so it stands up to malicious probing—SQL Injection is my top worry. Once the cleanup is finished, you’ll redeploy the patched build to my live PHP stack and confirm that all features operate normally under real traffic. A successful engagement means: • a brief, private report pinpointing each issue you discovered and how you neutralised it • a fully patched source tree returned to me, ready for version control • the application running stably on my server, with verification that the fixes prevent the SQL Injection vectors you identified Please come prepared with practical exploitation knowledge, the usual security ...

Project Overview I’m looking for an experienced WordPress developer to perform a forensic audit and cleanup of a site that previously used custom developer-created code and automation. After a hosting migration, the site experienced admin access issues, login loops, and plugin behaviour reverting unexpectedly. Hosting support stabilised access but confirmed that custom plugins and non-standard configurations existed and fall outside their support scope. An automated deployment mechanism has been removed, but I need confirmation that no residual scripts, hooks, or configurations remain that could overwrite files, revert settings, or affect admin access. Scope Audit custom plugins, theme code, and mu-plugins Check for role/capability filters and forced redirects As...

My private server farm runs entirely on Windows Server 2019/2022 and I want a single, reliable point of contact to keep it both secure and resilient. Day-to-day, you will be hardening the network with advanced threat-detection practices—think real-time log analysis, strict firewall policy reviews, prompt patching, and well-documented incident response plans. All data protection flows through Veeam. I rely on daily image-level backups, off-site replication, and periodic restore tests, so you’ll need to stay on top of job success reports, storage consumption, and any failure remediation without waiting for me to ask. Support is part of the arrangement: when an issue or change request lands in the ticket queue, I expect timely follow-through and clear communication until closure...
