How a Pharma Giant Turned a Past Attack into a Proactive Defence

Problem Statement

Three years ago, disaster struck. A ransomware attack crept silently into the systems of a leading pharmaceutical manufacturer. In just hours, screens went dark, production lines stalled, and critical research data was locked behind unbreakable encryption. The financial loss was heavy. The reputational cost, even heavier. They paid the price once — and vowed never to pay it again.

But in cybersecurity, memory can fade, and threats can evolve. With operations spread across multiple manufacturing sites and a complex web of IT and OT systems, the company faced a truth: If they didn’t keep checking their walls, the attackers would eventually find a new way in.

Our Approach

When they called Alliance Pro, we knew this was not a routine check — it was a mission to ensure history would not repeat itself

We launched a full-spectrum cybersecurity posture assessment, combining:

01

Grey Box Vulnerability Assessment & Penetration Testing

To think like an attacker and find cracks in their armour

03

Firewall Rule-Set Analysis

To hunt for overly permissive rules that could be an open door to attackers

02

Configuration Reviews

scanning servers, endpoints, network devices, and firewalls for misconfiguration that silently weaken defences

04

OT Firewall Security Checks

Making sure their manufacturing control systems were locked down against lateral movement from IT networks.

Our Story

Founded by passionate pet lovers, Porto Pet was born from a desire to create a one-stop-shop for all pet-related needs. We understand the joy and companionship that pets bring into our lives, and we are committed to offering high-quality products and services that reflect that love and care.

Tech Stack Used

OWASP, PTES, NIST 800-115 for structured, attack-based testing.

CIS and CERT-IN for configuration hardening.

– Microsoft 365, Zscaler ZIA, SentinelOne, Checkpoint HEC

to validate vulnerabillties and anticipate attack patterns

Turning Point

Halfway through the engagement, the scans told a story — one the client didn’t want to hear. Hidden deep in the network, we found vulnerabiliƟes and misconfiguraƟons that could have been the perfect stepping stones for another ransomware aƩack. A misconfigured firewall rule here. An OT access gap there.

Individually, they were small. Together, they were a map straight to the company’s crown jewels. That’s when the leadership realized: This was not about finding problems — it was about stopping the next attack before it started.

Scope & Actions Taken

Reviewed and tested over 1,000 devices across IT and OT environments

Corrected misconfigured firewalls and tightened access control

Segmented IT and OT networks to block lateral movement

Enforced best-practice security baselines across cloud and endpoint tools

Delivered a prioritised, actionable roadmap for remediation

Outcome

By the time we wrapped up, the company’s defences looked very different from when we started The gaps we found were closed, critical controls were in place, and the OT environment — the heart of their manufacturing — was far more resilient.

Today, they’ve made annual cybersecurity posture assessments a non-negotiable part of their operations

Customer Feedback

Three years ago, we were caught off guard. This Ɵme, we were ready — and we’ll stay ready. Alliance Pro didn’t just check our systems, they tested our future." — CISO, Pharma Manufacturing Firm

Key Takeaways

Cyberattacks don’t knock twice — they find a new window

Proactive security reviews turn past pain into future strength.

IT and OT must be secured together for true resilience.

Small misconfigurations can be the weak link in a strong chain.
