• • Packet analyzers and scanners: I used Wireshark, Tcpdump, Nmap, and Nessus for network troubleshooting, vulnerability assessment, and security auditing.

  • Virtualization and Simulation: I deployed VMware Workstation, VirtualBox, and Hyper-V to build and manage virtual lab environments; I simulated and tested network design scenarios with GNS3, EVE-NG, Cisco Packet Tracer, Visio, and Draw.io.

  • Programmability and Automation: I automated network deployments and configuration using Python, Ansible, Git/GitHub, PowerShell, Go, C, C#, Nautobot, Rust, Bash Shell and .Net Core. I integrated and managed network automation workflows with Cisco DNA Center, and NetBrain.

  • Monitoring & Performance Optimization: I deployed Zabbix, Tcpdump, WhatsUp Gold, NTopng, Nessus, Wireshark, Zeek, Nagios, PRTG, and SolarWinds to monitor enterprise networks, servers, and applications, databases, and virtual environments.

  • Security and penetration testing: I strengthened defenses with Snort, SecureCRT, Metasploit, Palo Alto Cortex XDR, Nmap, and WinSCP, detecting vulnerabilities and improving incident response.

  • Remote access and connectivity: Use PuTTY, VPNs, Secure Shell (SSH), Cloud/Web-Based Access, Virtual Network Computing (VNC),  and PING for secure device access and connectivity testing across all environments.

• • Intrusion Detection & Prevention Systems (IDS/IPS) – I monitor and secure network traffic using Snort, Elastic Stack, Suricata, and Zeek, detecting anomalies and potential intrusions. 

  • Vulnerability Scanners – Using Nessus, OpenVAS, and QualysGuard, I perform vulnerability assessments to identify system weaknesses before exploitation. 

  • Network Traffic Analysis – I leverage Wireshark, tcpdump, and NetFlow for packet-level analysis, root cause identification, and forensic investigations.

  • Log Management Tools – I have experience with Graylog, Elastic Stack, and Sumo Logic to collect and analyze logs for anomalies and incident correlation.

  • Malware Analysis Tools – I analyze suspicious files using Cuckoo Sandbox, Any.Run, and VirusTotal, helping to determine indicators of compromise (IOCs).

  • SOAR Platforms – I automate and orchestrate incident response with Cortex XSOAR, IBM Resilient, and Splunk SOAR, improving SOC efficiency.

  • SIEM Platforms – I have used Splunk, Wazuh, QRadar, ArcSight, and ELK Stack for centralized log collection, correlation, and real-time security monitoring.

  • Case Management / Ticketing Tools – I manage and track incidents with ServiceNow, JIRA, and TheHive, ensuring proper escalation and resolution.

Strong capability in working with enterprise networking hardware to build, maintain, and optimize reliable network infrastructures.  

Practical knowledge of essential networking tools such as cable testers, crimping tools, punch-down tools, tone generators, loopback adapters, console cables, and diagnostic equipment used for infrastructure deployment, fault isolation, connectivity verification, and performance validation.

These tools play a critical role in improving network stability, reducing downtime, accelerating troubleshooting processes, strengthening infrastructure reliability, and supporting secure communication across business operations. Their effective use contributes to faster issue resolution, cleaner installations, improved signal integrity, enhanced operational efficiency, and long-term network scalability.
