I need an external, black-box penetration test carried out against three separate /24 IPv4 ranges that power our public-facing web applications, email servers, and SIP services. The exercise must satisfy our compliance requirements, so the methodology, evidence gathering, and final reporting all have to stand up to an audit review. Here’s what I expect: • Reconnaissance, vulnerability discovery, and controlled exploitation performed strictly from an external perspective—no inside credentials will be provided. • Clear scoping and scheduling so the assessment covers every live host across the three networks without disrupting production traffic. • A written report that prioritises findings by risk, maps them to relevant compliance controls, and includes reprod...

Our in-house team is wrapping up a custom lending portal that consolidates every stage of the loan lifecycle and provides separate dashboards for investors, borrowers, and brokers. Because the platform stores and exchanges highly-sensitive documents—personal IDs, financial records, and legal agreements—I need an independent specialist to run a single, thorough security review right before we move to production. My top priority is verifying that data encryption is rock-solid at rest and in transit. In addition, each role (investor, borrower, broker) has its own workflow, so you’ll need to confirm that our access-control logic keeps information strictly segregated. What I expect from you • Pen-test and code-level review focused on encryption implementation (TLS, ke...

I need a proven strategy to move more than 10 TB of mixed-type data—media assets, databases (primarily MSSQL dumps) and a variety of project files—across our WAN as quickly and safely as possible. The current link struggles with long round-trip times and occasional packet loss, so every transfer drags on for days and sometimes fails outright. My aim is threefold: slash the overall transfer window, eliminate checksum mismatches or corrupt segments, and lighten the ongoing load on the network while these moves are in progress. I am open to any combination of protocol tuning, compression, data deduplication, forward-error correction, WAN acceleration appliances, or cloud relay services—as long as the end result delivers measurable improvements. Deliverables • D...

I need a qualified security-systems technician to fully wire and commission a new burglary alarm in a commercial space. The system must protect every entrance, exit and street-facing window, tie into motion detectors for interior coverage, and integrate with a small network of surveillance cameras that record to an on-site NVR. The building is already roughed-in with conduit runs but no cabling. You will supply and pull the appropriate alarm cable, terminate it cleanly at the control panel, install door/window contacts, PIR motion sensors and four PoE cameras, then program the panel so that all zones report correctly. Final steps include walk-testing each sensor, demonstrating camera feeds at the NVR and handing over a simple zone map. Successful delivery means: • All zones and came...

I am moving our production DNS from a Windows-based server to a fresh Debian instance running Bind9. The new host needs to be fully authoritative for all current zones, so I will rely on you to extract every record from the Windows server, import them into Bind-compatible zone files, and validate that the answers match bit-for-bit before cut-over. Once the zones are in place, I also want DNSSEC enabled with a properly generated Key Signing Key (KSK) and Zone Signing Key (ZSK) for each zone. Please configure automatic key rollover and publish the DS records I will provide to my registrar. The goal is a seamless switchover with zero client disruption and clean validation on tools like dig +dnssec, dnsviz, and Verisign’s DNSSEC debugger. Deliverables • Debian 12 server with Bind9...

My Juniper EX Series switch has suddenly stopped loading the web interface after I made some configuration changes. The CLI is still reachable, but the browser page never appears, so I can’t use J-Web for day-to-day management anymore. I need an engineer who knows EX Series internals to: • Diagnose why the GUI service will not start or respond. • Roll back or adjust the recent configuration edits—without disrupting live traffic—to restore full J-Web access. • Provide a short note outlining what was fixed so I can avoid the problem next time. Ideally we can screen-share or you can guide me over SSH; I’m ready to supply current config snippets and logs on request. Once the GUI loads normally again and I can log in through a browser, the job is d...
