With 15+ years steering large Cisco and Fortinet networks, I’ll start with a crisp Discovery & Assessment of your 100 Cisco switches, FortiGate HA, multi-ISP routing, and enterprise Wi‑Fi. Expect a clean Current‑State map, a Future‑State blueprint, and a risk register you can actually use. My delivery blends hands‑on tuning with thorough documentation and workshops to empower your IT team. I will focus on reducing risk, tightening segmentation, and strengthening security posture while preserving agility for 1,500+ users. I’ve led enterprise-scale initiatives around Network Administration, fortifying Network Security, and enabling robust Network Monitoring in parallel. The plan is practical: validate routing, VLAN design, HA failover, and VPNs; align security policies with best practices; and create clear implementation priorities with business impact. I bring enterprise‑scale experience and a bias for measurable outcomes. The proposal includes current‑state diagrams, a gap list, and a prioritized roadmap with milestones and success metrics. I’m ready to start with Phase 1 assessment and progress to testing, validation, and knowledge transfer. Do you prefer a staged 'pilot light' rollout for the Fortinet/Cisco changes, or a full-blown fireworks show (big-bang cutover)? Any must-test failover scenarios you want baked in?

@Appworldz

Hi, I’ve led enterprise network assessments and optimization work across Cisco campus environments and Fortinet security stacks, including FortiGate HA clusters, multi-ISP routing, VLAN segmentation, and large scale enterprise LAN/WAN architectures. My approach is very structured: I start with deep discovery (routing, switching, firewall policy, HA and failover paths), then build a clean gap analysis aligned to Cisco and Fortinet best practices, followed by a prioritized remediation roadmap that your internal team can execute safely. I also produce clear network diagrams, risk registers, and executive plus technical reports that make complex environments easy to understand and act on. Estimated Budget: $1,200 CAD Estimated Timeline: 7 to 10 days (assessment + documentation phase) Optimization and implementation tuning can be extended as a second phase if needed. Sahanaj

Whats up Boss I have strong hands-on experience with Cisco enterprise networks, FortiGate HA clusters, routing, VPNs, VLAN design, firewall hardening, and large-scale infrastructure troubleshooting. I can perform a full assessment, identify risks/misconfigurations, optimize performance, and provide clear enterprise-grade documentation. I’ve worked with environments involving complex Layer2/Layer3 architecture, failover, security audits, and network optimization. Quick question: Is your current environment running **SD-WAN on Fortinet, and do you already have existing network diagrams/documentation available for review?

@nintysix96

Rough placeholders on the bid amount and timeline -- we will sharpen both once we have a proper look at your environment and scope. From what you have described, this is a full-picture enterprise network review across a campus with around 100 Cisco switches in a tiered architecture, a FortiGate HA cluster handling multi-ISP termination and SD-WAN, and over 1,500 users depending on it daily. The end goal is not just a checklist -- you want a clear picture of where the risks actually sit, what is misconfigured versus what is by design, and a prioritized path to fix what matters most before something breaks in production. Here is how we would approach it: - Discovery and documentation: Pull running configs from switches and FortiGate units, map the actual Layer 2 and Layer 3 topology, and cross-check it against what is supposed to be there. Gaps between design intent and live config are usually where surprises hide. - FortiGate HA and SD-WAN review: Validate HA sync state, ISP failover logic, SD-WAN rules, VPN tunnels, NAT policies, and firewall policy ordering. FortiGate policy bloat and shadow rules are a common source of both security holes and performance drag. - Cisco switching assessment: STP topology validation, VLAN hygiene, trunk consistency, redundancy paths, and storm-control settings across Core, Distribution, and Access layers. - Security posture and segmentation: Review network segmentation against what your security policy actually requires, check monitoring and syslog coverage, and flag any flat or under-segmented zones. - Gap analysis and final report: Deliver a written report ranking findings by severity, with clear remediation steps and business justification for each change -- not just a raw config dump. Once we align on scope and access logistics, we will send a proper proposal document with a phased breakdown, timeline, and firm pricing. Want to jump on a quick call this week to walk through the environment and confirm what access we would need? Best, 96 Studio

@builtm7

Hi Riyadh, I will deliver a current-state assessment report with a prioritized gap analysis and both current and recommended network diagrams, first draft inside three weeks, working US hours and in English and Spanish. You are running a large Cisco campus and a FortiGate HA cluster with multiple ISPs, and you want an honest, evidence-based read on what is solid, what is risky, and what genuinely needs to change before anyone edits a config. I have 15-plus years in enterprise IT and infrastructure, including zero-downtime email and server migrations. One question: do you already have current configs, diagrams, and read-only access available, or should the first milestone include discovery and inventory from scratch? I would run this as fixed milestones, starting with a paid discovery and assessment milestone so you see the findings and the technical and business justification before approving any optimization work.

@SunilKr1404

Hi, I reviewed your project requirements for Cisco and Fortinet Enterprise Network Assessment, Optimization, and Documentation. Your environment includes Cisco Core/Distribution/Access architecture, FortiGate HA firewalls, SD-WAN, VPNs, and enterprise wireless infrastructure. I have hands-on experience working with enterprise network and security environments, including network assessment, firewall policy review, routing optimization, VPN troubleshooting, high availability validation, and technical documentation. For this engagement, I would follow a structured approach: ✔ Review current network and security architecture ✔ Analyze routing, switching, SD-WAN, firewall, NAT and VPN configurations ✔ Identify performance, security and resiliency gaps ✔ Validate HA, redundancy and failover mechanisms ✔ Review monitoring, logging and operational processes ✔ Deliver detailed recommendations and future-state design documentation I can provide clear executive and technical reports along with network diagrams and prioritized remediation recommendations. A few questions: Approximately how many sites/branches are included in the assessment? Is the SD-WAN deployment fully operational or currently being optimized? Are updated network diagrams available, or would they need to be created during the engagement? I would be happy to discuss the environment in more detail and share my approach for delivering the assessment. Regards, Sunil Kumar
