Pruebas de Penetración Jobs

I’m looking for an experienced ethical hacker to probe my hybrid network—both wired and wireless—with the sole aim of uncovering security vulnerabilities. Scope and focus • Map the entire network topology, including any VPN entry points, routers, access points, and key servers. • Perform vulnerability scanning and targeted penetration testing against internal and external segments. • Validate findings through exploit proof-of-concepts where safe and appropriate, ensuring no disruption to production traffic. Deliverables 1. A clear, prioritized vulnerability report that explains each issue, its risk rating, and the affected assets. 2. Screenshots or logs that support every critical or high-risk finding. 3. Action-oriented remediation recommenda...

Objectives • Obtain an independent, manual penetration test to validate the security of the Selcomm platform and the isolation of customer environments. • Produce a formal report (with a redactable version) to evidence security assurance to enterprise customers. Environment (context) Solution: Selcomm billing platform — dedicated (non-cloud) software; virtualised Windows + Linux/Informix Hosting: Production: NTT data centre. Access/interfaces: Per-customer dedicated VLANs; site-to-site VPN; SSL/TLS and sFTP. No wireless Target list / scope (please price individually and combined) • A — External infrastructure: internet-facing VPN endpoint(s), any public web/portal, mail gateway. • B — Web application: authenticated & unauthenticated test of the Se...

I’m looking for a fresh, expert set of eyes on my already-launched SaaS. The priority is a thorough check of both Security and Performance. I’ll share the exact tooling, checklists, and testing methodologies I currently use so you can step straight into the review process without guessing which scanners, profilers, or penetration-testing suites to run. Here’s how I see the engagement unfolding: you explore every security layer—from authentication flow to data storage—and benchmark performance under realistic load. When you’re done, I’d like a concise report that highlights the key findings, high-impact risks, and the quick wins that will give me the most immediate improvement. No need for a long-form narrative or slide deck; a sharply written summ...

I’m ready to invest time in practical, one-on-one guidance that demystifies how attacks really unfold and, more importantly, how to spot and stop them. My background is purely beginner, yet my responsibilities will soon include supervising an IT/security team, so I need a clear, experience-based understanding of the attacker’s mindset. Focus areas • Network security: packet sniffing, basic exploitation, lateral movement, and network-level hardening. • Social engineering: phishing set-ups, pretexting scenarios, and the defense playbook that counters them. Learning format We will work inside pre-configured virtual machines you supply, where you walk me through the build-break-fix cycle: launching a representative attack, detecting it with common tools (Wireshark...
