| Problem | Traditional Approach | SideChannel Fix |
| ISE “pilot” never scales | One all-or-nothing deployment after six months of design meetings. | Agile rollouts—guest Wi-Fi onboarding in two weeks, then posture checks, then segmentation. |
| Tool shelf-ware | NAC policies written once, forgotten, and bypassed. | Continuous policy-tuning sprints with our vCISO & Network Security Engineers. |
| Shadow IT & rogue devices | Manual MAC filters and switchport shut commands. | Automated profiling + dynamic VLAN/Security Group Tags driven by ISE. |
| Audit gaps | Last-minute screenshot scramble. | Built-in evidence packs mapped to SOC 2, NIST CSF v2.0, CIS v8 and more. |
* Rapid assessment of network security architecture, Wi-Fi, and identity infrastructure. Contextualized findings and tangible recommendations provided to your team.
* AnyConnect/Secure Client posture checks—OS patch level, AV status, disk encryption.
* Dynamic VLAN or Scalable Group Tag (SGT) assignment at login.
* PAC files or Umbrella DNS for off-network protection.
* TrustSec/SGACL or SD-Access fabric micro-segmentation.
* API-driven ticketing integration (ServiceNow, Jira) for automatic device quarantine.
* Continuous compliance dashboards and tabletop exercises.
SideChannel’s policy templates come pre-mapped to common controls—think NIST AC-1, CIS v8 IG2. Auditors get the evidence they need; your team gets hours back.
From Series-A fintechs to regional healthcare providers, our NAC playbooks flex to your risk profile and headcount.
Our team of former CISOs brings decades of experience securing public-sector agencies, Fortune 500 enterprises, and high-growth startups alike. They’ve led programs in healthcare, finance, defense, and critical infrastructure—so they understand not just technical controls but also the operational realities of compliance and board reporting. Their guidance ensures your Cisco NAC deployment is grounded in real-world risk management, not theory. When you work with SideChannel, you get strategic leadership that’s seen it all—and knows how to make security stick.
Integrated capabilities of vulnerability management, certificate management, secure web gateway, micro segmentation shrink your attack surface and simplify compliance. Enclave’s micro segmentation enforces least-privilege access by default, while certificate management keeps device authentication strong and audit-ready. Continuous vulnerability scans feed risk scores into compliance dashboards, and the secure web gateway ensures policy-aligned internet use—creating a closed loop of visibility, enforcement, and proof for regulators.
| Pitfall | Why It Happens | Our Guardrail |
| Posture loops | Duplicate remediation VLANs mis-sending DHCP renewals. | Pre-flight lab testing with CML and Spirent. |
| ISE certificate chaos | Self-signed or expired keys block supplicants. | Automated ACME renewal with internal PKI. |
| Floods of “allow all” exceptions | Helpdesk overload post-enforcement. | Staged VLANs + user-friendly self-remediation portals. |
Cisco’s NAC stack is powerful, but configuration alone doesn’t equal control. You need the right people, process, and continuous tuning to turn features into risk reduction.
SideChannel supplies the experts, playbooks, and leadership to get you there—fast.
Book a 30-minute strategy call and discover how our zero-trust enclave platform and phased NAC programs can shrink your attack surface without shrinking your team’s bandwidth.
Traditional NAC projects often stall during long planning phases. SideChannel rolls out quickly, starting with guest onboarding, then layering posture checks and segmentation. This phased model gives you faster protection without waiting months for full implementation. It’s designed for smaller teams who need real outcomes sooner, not theoretical designs later.
Instead of relying on manual MAC filters or switch commands, SideChannel uses automated profiling and dynamic VLAN or Security Group Tag assignment through Cisco ISE. This approach adapts in real time, limiting access for unknown devices without constant manual intervention from your team.
Compliance is built in from the start. SideChannel provides policy templates already mapped to frameworks like SOC 2, NIST CSF, and CIS v8. Evidence packs are generated as part of the process, so you’re not chasing screenshots during an audit or scrambling to prove controls are in place.
The rollout includes five key steps: discovery, design, deployment, tuning, and evolution. This means SideChannel starts with mapping infrastructure, then applies policies in phases. Weekly tuning and dashboard reviews follow, and over time, the strategy expands to cover cloud identities as well.
SideChannel proactively stops misconfigurations like posture loops and expired ISE certificates, which can cause outages or policy gaps. Lab testing, automated key renewal, and staged enforcement policies help keep NAC controls running smoothly without overwhelming help desks or breaking connectivity.
