Network Security & SASE

Multi-vendor security without the lock-in.

We architect, deploy and operate network security across the vendors you already trust - Cisco ISE, Palo Alto Prisma, Fortinet, Zscaler, Cato, Check Point, Aruba ClearPass. The right tool for the segment, not the one a channel deal forces us to push. 100% endpoint migration delivered for financial and government clients on Cisco ISE.

The honest framing

Security isn't a vendor logo. It's a set of engineering decisions you have to live with for ten years.

Every vendor's marketing claims their platform "does everything." None of them actually does. The right architecture mixes vendors deliberately - the firewall vendor you trust at the perimeter, the NAC platform your team can operate, the SASE provider whose POPs are close to your users, and the segmentation enforcement that fits your compliance regime.

We're vendor-certified across every platform on this page, and we will tell you when one is wrong for your environment - even when it's the one you came in wanting. The engagements that work are the ones where the architecture decisions are made *before* the procurement cycle, not after.

What we deliver

End-to-end network security, from access layer to cloud edge.

/ 01

Cisco ISE deployment & migration

Greenfield ISE 3.x designs, migrations from ACS or competing NAC platforms, and 802.1X enterprise rollouts. Distributed deployments with PSN sizing, certificate lifecycle, posture, profiling and TACACS+ administration migration. Co-managed and fully managed operations available post-deployment.

/ 02

Multi-vendor SASE rollouts

Architecture and deployment for Palo Alto Prisma Access, Fortinet, Zscaler, Cato and Netskope. POP selection, identity-provider integration, ZTNA policy design, CASB and DLP rule engineering. We design the policy first; the vendor follows from the requirements.

/ 03

SD-WAN architecture & deployment

Palo Alto Prisma SD-WAN, Fortinet Secure SD-WAN, Aruba Silverpeak, Cisco Viptela and Versa. Underlay design, application-aware routing, hub topology, MPLS displacement plans and security integration with the SASE layer. Multi-site SD-WAN with diverse backhaul and policy-based routing.

/ 04

ZTNA & zero-trust access

Zero-trust network access deployments using Zscaler ZPA, Prisma Access, Cisco Duo, Okta and Cloudflare Access. Identity-aware proxy design, application segmentation, posture-based access policies and legacy VPN displacement. ZTNA that the business actually adopts, not a pilot that languishes.

/ 05

NGFW migration & policy rationalisation

Migrations between Cisco ASA / FTD, Palo Alto, Fortinet, Check Point and Juniper SRX. Policy extraction, deduplication, rule cleanup and translation. We don't lift-and-shift broken policy onto a new platform - we clean it first.

/ 06

Microsegmentation & compliance

VLAN, ACL, ISE-enforced and microsegmentation strategies for PCI-DSS, HIPAA, NIST 800-53 and ISO 27001 regimes. Network-side controls that map to your audit framework, with evidence packs that auditors actually accept.

Selected work

100% endpoint migration across 23 branches. Cisco ISE 3.x. Financial & Government.

A regulated financial-services client and, separately, a government agency engaged us to migrate from legacy MAC-bypass authentication to 802.1X with Cisco ISE. Both organisations had 20+ branch sites, mixed-vendor endpoints, and zero tolerance for production disruption.

We delivered a distributed ISE 3.x deployment with regional PSNs, designed certificate-based authentication for managed endpoints with MAB fallback for IoT, and rolled out 802.1X site-cluster by site-cluster with rehearsed rollback at each phase. Both engagements hit 100% endpoint migration coverage on schedule. Documentation was good enough that the in-house teams ran the platform post-handover without further engagement.

How we work

Security engagements run on disciplined phasing. Every phase has an exit gate.

/ Phase 01

Architecture & vendor selection

Threat model, compliance map, identity-source inventory, traffic-flow analysis. Vendor selection emerges from the requirements - not a pre-decided shortlist.

/ Phase 02

Policy engineering

Policy extraction from legacy, deduplication, role-based access design, posture rules, ZTNA application catalogue. Clean policy, codified.

/ Phase 03

Lab build & validation

Full lab with identity provider, sample endpoints, failover scenarios and audit-evidence capture. Cutover plans rehearsed before they touch production.

/ Phase 04

Phased production rollout

Pilot site or pilot user group first. Validation gates. Then site-cluster phasing with monitoring and rollback procedures. No big-bang cutovers.

/ Phase 05

Handover, runbooks & hypercare

Operational runbooks, monitoring dashboards, audit evidence packs, training for your team and 30/60/90 hypercare. Or we stay on as co-managed operators.

Frequently asked

The questions security leaders ask us first.

What's the difference between SASE and SSE, and which do we need?

SASE (Secure Access Service Edge) combines network connectivity (SD-WAN) with cloud-delivered security (SWG, CASB, ZTNA, FWaaS). SSE (Security Service Edge) is just the security half - no SD-WAN. If you already have a strong SD-WAN, SSE is the lighter rollout. If you're refreshing both at once, full SASE is the better economic call. We'll walk you through which fits your topology and TCO model.

How long does a Cisco ISE deployment typically take?

A greenfield ISE deployment runs 8 to 16 weeks. A migration from Cisco ACS or another NAC platform runs 12 to 24 weeks because policy translation and endpoint phase-in require careful sequencing. 802.1X rollouts across distributed sites usually phase by site cluster over 3 to 9 months. We size every engagement against your endpoint count, authentication source and downtime tolerance.

Can you migrate us off Cisco ASA / FTD onto another vendor?

Yes - and frequently do. The hardest part of any firewall migration is policy translation and rule rationalisation. We extract, deduplicate and clean policy before it ever touches the new platform. Common migrations we handle: ASA to Palo Alto, ASA to Fortinet, FTD to Palo Alto, and Check Point to Palo Alto or Fortinet.

Which SASE vendor should we pick - Palo Alto, Fortinet, Cisco, Zscaler or Cato?

Palo Alto Prisma is the most feature-complete and the choice for security-led organisations. Fortinet wins on cost and is excellent if your security team already runs FortiGate. Zscaler is the strongest SSE-only play and pairs well with any SD-WAN. Cato is best for greenfield SASE on a single vendor. We are not tied to any of them - the right answer depends on your existing stack, your team's skills and your contractual situation.

Can you operate ISE or our SASE platform after deployment?

Yes. We offer co-managed and fully managed engagements for Cisco ISE and the major SASE platforms - policy changes, certificate lifecycle, posture updates, identity-source integration, troubleshooting. You either own the platform with us on retainer, or we operate it and brief your team monthly.

Do you do incident response and forensic work?

We do network-side incident response: lateral-movement isolation, segmentation enforcement, log forensics from the firewall and access layer, and post-incident architecture hardening. We do not do endpoint malware reverse engineering or legal forensic chain-of-custody work - for those we partner with specialist firms and stay in the network lane.
