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. #J-18808-Ljbffr
