Cybersecurity: Fortinet & pfSense Firewalls
Firewalls, access control, and hardening built around how BPOs, banks, and healthcare operators are actually secured.
Reference Architecture
How a deployment fits together.
Engagement Model
How an engagement runs.
Day 1
Configuration review of what is already running: firewall rules, exposed services, and access rights.
Ongoing
Hardening, patch management, and scheduled access reviews, with each change documented.
Escalation
A defined incident path: isolate, diagnose, restore, then a written post-incident summary.
Our Approach
Security work here means configuration you can audit, not a checkbox. We harden what is already running before we recommend anything new, and we document every change we make.
What's Included
Firewall Deployment & Hardening
Fortinet perimeter security: policy configuration, rule auditing, and hardening of what is already in place.
pfSense-Based Security
pfSense firewalls for perimeter security, VLAN segmentation, and VPN termination where a full commercial appliance is not the right fit.
Access Control Systems
Role-based access, with biometric and card-based entry integration for physical and network access.
Endpoint Protection
Antivirus, patch management, and device compliance across managed endpoints.
Security Audits & Hardening
Configuration review and hardening of servers, network devices, and exposed services.
Secured Remote Work
VPN-gated access and least-privilege policy for remote and hybrid staff.

GitLab CVE-2026-85706: the CVSS 10 file-read flaw under attack, and why patching is only half the fix
An unauthenticated path traversal in GitLab's repository APIs lets attackers read any file the GitLab process can read, and CISA confirmed exploitation within a day of the patch. The timeline, the exposure figures, the root cause, and the secret rotation that has to follow the upgrade.

Prompt injection in business systems: protect the step after the answer
A malicious instruction in a ticket or document becomes dangerous when it can influence tools, recipients or permissions. Focus the defence on what the connected application can do.
