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 adecuado 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.
