Hi Boss A few questions: * Approximately how many servers, endpoints, and network devices are in scope? * Will VPN/external-facing assets also be included? * Do you require both black-box and authenticated internal testing? Once I know the network size and scope, I can confirm the timeline and approach. Thanks.

Thank you for the clear scope. This is a well-defined hybrid assessment, and I can approach it methodically to minimize disruption while producing actionable findings. I would start with scoping and a testing window confirmation, then map the external and internal attack surface across wired, wireless, VPN, routers, access points, and key servers. From there, I’d run controlled vulnerability scanning, validate priority issues with safe proof-of-concepts where appropriate, and document evidence for each critical or high-risk item. You’ll receive a concise report with prioritized findings, affected assets, risk ratings, screenshots or logs, and practical remediation steps your team can execute quickly. I also work with responsible-disclosure standards and can align with NDA requirements before testing begins. If helpful, I can structure the engagement around low-noise discovery first, then targeted validation to keep production traffic stable throughout the assessment.

Hi, I'm Fernando, founder of FCyberSecurity LLC. I run my own vulnerability scanning platform, independently benchmarked against the OWASP Benchmark with zero false positives in controlled testing. For your hybrid network assessment, my approach: 1. Map the full network topology (VPN entry points, routers, access points, key servers). 2. Vulnerability scanning + targeted penetration testing (internal and external segments) using Nmap, Nessus, Wireshark, Metasploit. 3. Safe proof-of-concept validation on critical/high findings only, with zero disruption to production traffic. 4. Deliver a clear, prioritized report with risk ratings, evidence (screenshots/logs), and actionable remediation steps your team can implement directly. Happy to sign an NDA before starting. I can begin as soon as we agree on the testing window. Quick scoping questions: how many public-facing IPs/domains, internal subnets, and wireless SSIDs are in scope? Would you prefer a black-box or gray-box approach, and is there a preferred testing window to avoid production impact?

Hi there! Quick question: are you looking to test against any specific compliance frameworks like PCI-DSS or HIPAA, or is this more of a general security baseline assessment? Regardless, this is definitely something that I feel confident delivering on, given my past experience. I would love to discuss your project further! Looking forward hearing from you. kind regards, Corné

Hi, I am an independent security researcher and penetration tester. For your hybrid network I would work in three stages. 1) External: enumerate public IPs, VPN entry points, and exposed services with Nmap and targeted manual testing, looking for outdated software, weak remote-access and VPN configuration, and exposed admin interfaces. 2) Internal: authenticated and unauthenticated vulnerability scanning of routers, access points, and key servers, followed by safe, non-destructive proof-of-concept exploitation to validate real risk with no impact to production traffic. 3) Wireless: review of access point configuration, encryption, and network segmentation. You will get a prioritized report with a clear risk rating and the affected assets for each issue, screenshots or logs for every critical and high finding, and remediation steps your in-house team can action. I follow responsible disclosure, respect an agreed testing window, and can sign an NDA. Two of my vulnerabilities have been resolved and publicly disclosed by Sony, and I report on HackerOne, Bugcrowd, and Intigriti. Two quick questions so I can be precise: how many public IPs, internal subnets, and wireless networks are in scope, and for the internal and wireless parts will you provide VPN access or an on-site jump host, or would you prefer I propose a small remote testing setup? I can start within your window and deliver in about 7 days.
