Firewall administration & security specialist
aug 2, 2025 - senior
$3,500.00 fixed
project summary
we are seeking an expert firewall administrator to perform a comprehensive security audit and overhaul of our network perimeter. This project is a critical initiative to enhance our defenses, streamline our firewall policies, and establish a robust, proactive security posture against modern threats.
the business imperative & our security challenges
our current network security is not meeting the demands of our growing business. We are facing several critical challenges that must be addressed:
* complex & unmanaged rulebase: our firewall rule set has become overly complex and lacks proper documentation, making it difficult to manage and prone to errors.
* lack of proactive threat hunting: we are in a reactive security stance, relying on alerts rather than actively searching for and neutralizing potential threats.
* suboptimal vpn performance: our remote access and site-to-site vpns are unreliable and slow, hindering business operations and frustrating our remote teams.
* compliance gaps: we lack the detailed logging and auditing capabilities necessary to easily meet our industry's compliance standards.
required expertise & technical skills
we require a specialist with deep, hands‑on experience and a strategic mindset. The ideal candidate must possess:
* core firewall platforms: proven expertise with one or more of the following: palo alto networks, fortinet, or cisco asa/firepower.
* security & networking concepts: a deep understanding of network security principles, including intrusion prevention systems (ips), intrusion detection systems (ids), and security policy lifecycle management.
* vpn technologies: in‑depth knowledge of ipsec and ssl vpns for both remote user access and site‑to‑site connectivity.
* proactive threat management: experience with vulnerability assessments, threat analysis, and implementing proactive security measures.
* compliance & documentation: the ability to implement and document configurations that align with major compliance frameworks.
scope of work & key deliverables
the project will involve a full‑scale audit and implementation plan, culminating in a hardened and optimized network perimeter. Key deliverables include:
* a comprehensive security audit report detailing current vulnerabilities and risks.
* a simplified and optimized firewall rule base, with clear documentation for each policy.
* a fully configured and documented vpn solution.
* a new logging and monitoring strategy to enhance threat visibility.
* a final report outlining all changes and recommendations for ongoing maintenance.
support & post-project expectations
beyond the project's completion, we expect a final knowledge transfer session with our internal team. This session should cover the new configurations, security policies, and best practices for ongoing firewall management. We also require a commitment to providing 1‑2 weeks of post‑project email support to address any unforeseen issues or questions that arise from the implementation.
