I need a clear, professionally-written blueprint that I can hand straight to my developers so they can begin building a cyber-security application. The document must spell out scope, objectives, high-level architecture and phased milestones while keeping two pillars front-and-centre: network security and data security. Key modules to be covered in the scope are user authentication, real-time threat detection and automated vulnerability scanning. For each of these I expect you to describe functionality, recommended technology stacks, integration points, basic data flows and any compliance considerations (e.g. NIST CSF, ISO 27001, OWASP). Diagrams—UML, context or sequence—are important where they add clarity. Please base the structure on industry best-practice documents: exec...
I need a certified ethical hacker to run a full-cycle social-engineering engagement focused exclusively on phishing simulation. The objective is to gauge how many employees interact with malicious-looking emails, identify patterns behind unsafe clicks or credential submissions, and turn those findings into actionable security awareness improvements. The work involves designing realistic phishing scenarios aligned with our business context, sending the campaign through a managed platform (GoPhish, King Phisher, or similar), silently harvesting the metrics, and then compiling a thorough post-test report. No destructive payloads or system exploitation are allowed—this is a people-centric test only. Deliverables • Campaign design document outlining themes, targets, schedule, and...

What matters most is deep, practical knowledge of ISO 27001. Familiarity with ISO 27005 and the NIST frameworks is important because we want our risk management and control mapping to stand up to external scrutiny. Certifications such as ISO 27001 Implementer, ISO 27005 Risk Manager and any I...
I need an experienced cyber-security professional who can move straight past theory and actually put the right protections in place. My environment is already running, but the current safeguards are piecemeal. Your task will be to evaluate what is there, decide what is missing, and implement the controls that close those gaps—whether that involves configuring firewalls, hardening servers, enforcing least-privilege access, deploying endpoint protection, or setting up logging and alerting in a SIEM. I’m looking for measurable improvements, not just a written report. Once the new measures are live, I’ll need clear documentation of every change plus a brief hand-over session so my in-house team can maintain what you install. Deliverables • Security controls fully dep...
I need a skilled network engineer to spend one full day at my client’s office acting as our hands-on field resource while my remote team drives the configuration work.

I'm looking for someone who understands how to configure a GL-iNet GL-MT6000 (Flip 2) router to connect to and work through a foreign VPN. I need to understand what settings to use, which provider/hosting provider to use, and which package to choose to connect the VPN to the router. I also need to understand how to resolve potential leaks, stress testing, and so on. After connecting the router and installing the VPN, I need to make sure there are no issues that could reveal my current location, and that everything works reliably.
I’m looking for a specialist to run a full health-check on my Local Area Network. The priority is to verify that everything works as intended and to pinpoint any performance bottlenecks that might slow users down. Security is being handled separately, so your focus will be strictly on functionality and performance. The job involves testing end-to-end connectivity, measuring throughput and latency at peak and off-peak times, and confirming that current configurations on switches, routers, and access points align with best practices. I expect you to use industry-standard network diagnostic tools—think Wireshark, iPerf, or SolarWinds—but you’re free to bring in any utilities you trust as long as the results are clearly documented.

I have already completed the technical investigation of a recent security alert: the endpoint protection platform flagged an executable that tried to tamper with system files and phone home to an external server. I verified the hash, monitored live-system behaviour, confirmed the activity as malicious, quarantined the file and rescanned the host to ensure it is now clean. What I need next is a professionally written incident report that translates those raw findings into a clear narrative for both management and technical stakeholders. The document should outline the timeline of events, the investigation methodology, indicators of compromise, remediation actions taken, and practical recommendations to harden the environment against similar threats. Where helpful, map tactics to MITRE ATT&...

I hold written authorization from the system owner and need an experienced ethical-hacking professional to carry out a controlled breach of our production environment. The assignment goes beyond a traditional penetration test: I want you to replicate a real-world, end-to-end intrusion scenario so we can measure how our monitoring, logging and incident-response teams react under pressure. Scope • Obtain initial access using any non-destructive vector you discover (phishing simulation, misconfigurations, credential weakness, etc.). • Laterally move, escalate privileges and demonstrate data access without altering or deleting information. • Leave tamper-proof evidence (flags) in pre-agreed directories so we can verify compromise. • Conclude with a thorough report that det...

I’m ready to move from concept to a fully functioning Wide Area Network and need an experienced networking specialist to guide every step. The job starts with assessing my current sites and bandwidth needs, then designing a scalable WAN topology that keeps latency low and uptime high. From there you’ll source or specify the right hardware, configure routing, implement security policies, test end-to-end connectivity, and leave me with clear documentation so my team can handle routine maintenance. If you’ve rolled out multi-site WANs before and can communicate technical details in plain language, let’s talk timelines and milestones.
I’m putting together an in-depth, case study–style report on a real-world data breach that struck the healthcare sector. The goal is to walk readers through the timeline of the incident, the technical and procedural gaps that allowed it to happen, the immediate response, and the long-term remediation steps. Accuracy and authenticity matter: I will provide raw notes, public disclosures, and redacted internal memos once we start, but I’m relying on your cybersecurity and information-management expertise to shape them into a compelling, well-structured narrative. Here’s what I’m after: • A 3,000–4,000-word report formatted for executive readership but detailed enough for security teams. • Clear articulation of attack vectors, compromise indi...

We can meet on Zoom or Google Meet for 2–3 hours a week, preferably evenings or weekends. Deliverables • A structured lesson plan that maps out the sequence of sessions • Recordings or sess...
I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to imp...
