Firewall Design, Migration & Governance
Design, build and migrate firewall estates, then optimise and govern the rule-base so changes stay consistent and auditable.
CyberRoof advises on, designs, implements and audits network security, WAF and application delivery, SASE, enterprise and wireless networking, PKI and automation, delivered directly by a senior specialist.
Firewalls, segmentation and secure access designed so trust is never assumed and every change is governed.
Design, build and migrate firewall estates, then optimise and govern the rule-base so changes stay consistent and auditable.
Identity-centric access and micro-segmentation designs that remove implicit trust and limit lateral movement.
Platform migration and policy adoption for ZTNA and CASB, including replacing WSS with a Netskope SASE deployment and retiring legacy VPN for granular, identity-aware access.
Visibility and segmentation for unmanaged clinical and IoT devices, with automated endpoint detection and response.
Protecting and delivering web applications at scale, from WAF policy to load-balancer platform migrations.
Centralise WAF, CDN and DDoS protection on one platform, including migration from Vercara to Cloudflare, with tuned policies that reduce incident noise.
F5 design and lifecycle management, including ASM web application security policy, across Viprion and rSeries platforms.
Plan and execute migrations between load-balancer platforms with HLD/LLD, test plans and low-risk cutover.
Resilient wired, wireless and data centre networks, with access control built in rather than bolted on.
Design and review of campus, WAN and multi-data-centre networks, with routing, resilience and capacity built in.
Review and troubleshooting of enterprise Wi-Fi: 802.11 behaviour, controller and assurance telemetry, and secure onboarding.
Policy-based wired and wireless access with Cisco ISE: authentication and segmentation by identity and device type.
Secure connectivity between data centres and AWS or Azure: transit, routing, security groups and virtualised networking.
Replacing manual, error-prone change with pipelines, and running network and security operations to a measurable standard.
Terraform, Azure DevOps and Python pipelines that bring GitOps-style change control to firewall, load-balancer and network estates.
Certificate lifecycle governance and automation that removes expiry-driven outages across the estate.
Network mapping, firewall policy analysis and log analytics so teams can see change impact and risk before it bites.
Review and improve incident, problem and change processes, escalation paths and SLA performance for network and security teams.
Aligning technical controls with regulatory requirements and turning findings into a roadmap the business can fund.
Independent review of designs and HLD/LLD documents against policy, so security findings are caught before build.
Assessment against ISO 27001/27002, NIST and GDPR, with audit evidence support and a roadmap to close gaps.
Incident response and disaster recovery planning, plus penetration testing and vulnerability assessment oversight.
A prioritised network and security roadmap, with vendor-neutral platform selection and business cases for the investment.
Use one service or the full lifecycle, on any of the capability areas above.
Independent, vendor-neutral advice on architecture, platform choices and risk, so decisions are made on evidence.
Architecture and detailed design that can be built, operated and audited.
Hands-on build, migration and cutover, including the configuration, testing and handover.
Evidence-based review of firewalls, networks, WAF, PKI and controls against policy and frameworks.
Examples from regulated financial services, shared anonymously.
Migrated web application protection from Vercara to Cloudflare, centralising WAF, CDN and DDoS protection on one platform.
Deployed Netskope SASE to replace WSS, including ZTNA and CASB policy adoption for cloud application access.
Replaced F5 Viprion chassis with rSeries and introduced GitOps-style management with Terraform and Azure DevOps.
Governed the certificate estate through Keyfactor Command, with lifecycle automation across the estate.
Each tied to a clear outcome.
A targeted assessment or design piece with a clear, tangible deliverable (for example a Gap Analysis Report or an HLD/LLD). Fixed fee, fixed timeframe.
End-to-end delivery of a specific technical change, such as a WAF or SASE migration. Scoped by project phase and outcome.
Ongoing expert input to govern risk, review designs and support decisions, without a full-time hire.
Both. Engagements can cover advisory, design, hands-on implementation and audit, together or as separate pieces of work.
Every engagement is led and delivered by Vikas Shrivastav directly. There are no junior hand-offs and no account managers between you and the person doing the work.
No. CyberRoof has no reseller agreements, so recommendations follow your requirements. Hands-on experience spans Palo Alto, Fortinet, Check Point, Cisco, F5, Cloudflare, Netskope, AWS and Azure, but experience is not endorsement.
Audits and design pieces are a fixed fee for a fixed timeframe. Implementation is scoped by phase and outcome. Advisory retainers are scoped around the level of ongoing support you need.
Every engagement is scoped to a tangible outcome, for example a working migration, an HLD/LLD, a gap analysis report or a prioritised roadmap.
A direct 30-minute conversation about your challenge and environment. It is not a sales call, and if CyberRoof is not the right fit, you will be told.
