Zscaler ZIA Implementation in Saudi Arabia How Securze Delivered Zero Trust Security for a Multi-Geography Enterprise
The Story
The Kingdom of Saudi Arabia is in the middle of one of the most ambitious digital transformations in the world. Billions are being invested. New industries are being built. And at the centre of it all are organisations moving fast, hiring globally, deploying technology at scale, and operating across borders.
Speed, however, has a cost.
One such organisation, a high-growth digital joint venture operating at the intersection of enterprise IT and the energy sector, had built a workforce that spanned Riyadh, Mumbai, Dubai, and beyond. Employees, contractors, leadership. Windows machines, MacBooks, remote connections. Dozens of departments, each with different tools, different needs, different risk profiles.
What they hadn’t built was a security infrastructure that could keep up.
Not because they didn’t care. They did. But like most fast-scaling organisations, security had been treated as something to solve later. Policies were inconsistent. User access was managed manually. Internet traffic moved freely, with little visibility into what was going across the wire. A contractor, a phishing email, an unmonitored download, the exposure was real, and growing every day.
They needed a partner who understood both the technology and the stakes.
They chose Securze.
The organisation had grown rapidly, but its security infrastructure hadn’t kept pace. With employees, contractors, and leadership spread across Saudi Arabia, India, and the UAE, there was no single, unified layer of security governing how users accessed the internet. Policies were applied inconsistently across departments, and there was no way to distinguish what a contractor should access versus what a senior leader or an IT engineer needed. User accounts were managed manually, which meant that when someone joined or left the organisation, their access wasn’t always updated in time, creating invisible gaps that are a security team’s worst nightmare. On top of that, encrypted HTTPS traffic was moving across the network largely uninspected, leaving the organisation blind to malware, phishing attempts, ransomware delivery, and command-and-control communications hiding inside what looked like normal browsing. Cloud applications were being used across the organisation with no governance, no one truly knew which apps employees were logging into, what data was being uploaded, or where it was going. For an organisation operating in a high-stakes industry in a region with increasing cyber threat activity, this was not a sustainable position.
Securze deployed a full Zscaler Internet Access implementation, designed from the ground up to match the organisation’s structure, geography, and risk profile. The foundation of the deployment was identity. We connected Zscaler directly to the organisation’s Active Directory using SCIM and SAML 2.0, so that every user – from a new joiner to a contractor brought on for a short engagement, was automatically provisioned into the right security group the moment they were added to the directory, and automatically removed the moment they left. No manual intervention, no forgotten accounts, no access that outlives employment.
On top of that identity layer, we built department-specific internet access policies for every team in the organisation – IT, Sales, Marketing, HR, Leadership, Delivery, and Contractors. Each policy was crafted to give that team exactly the access they needed to do their jobs, while a global block rule running underneath eliminated entire categories of risk across the board, including anonymizers, peer-to-peer file sharing, high-risk domains, and content that has no place in a corporate environment.
Cloud application governance was implemented with the same precision. Approved productivity tools, AI applications like Microsoft Copilot and ChatGPT, and collaboration platforms like Microsoft Teams, Zoom, and WebEx were permitted. Everything outside that approved list was blocked. Social media access was restricted to the departments that have a genuine business reason for it. Streaming and unauthorised mail applications were shut down entirely.
We then turned our attention to the traffic itself. All HTTPS traffic is now decrypted and inspected through Zscaler’s Secure Web Gateway, with intelligent bypass rules in place for sensitive categories like healthcare and financial sites where privacy must be preserved. Twenty-four advanced threat protection controls were activated, covering everything from command-and-control server blocking and domain generation algorithm detection to phishing protection, geo-blocking of high-risk countries, and the elimination of anonymising tools like Tor. A cloud firewall rule was deployed to block QUIC protocol traffic, forcing all encrypted connections through inspectable TCP channels. A custom PAC file was configured to dynamically route each user’s traffic to the nearest Zscaler data centre, whether that’s Riyadh, Mumbai, Dubai, or Delhi, ensuring security never comes at the cost of performance.
Finally, a Browser Isolation profile was pre-staged and ready to activate in the event of an elevated threat scenario, and a ring-based update system was put in place to roll out Zscaler client updates to IT first, then the broader organisation, with zero disruption to daily operations.
The organisation now operates with a security posture that matches the scale and ambition of its business. Every user, on every device, in every location, passes through a consistent, policy-enforced security layer before touching the internet. Identity management that once required manual effort now runs automatically, with user provisioning and de-provisioning tied directly to Active Directory. Over forty user groups are governed by role-based policies that reflect real business needs rather than blanket rules. All internet traffic is inspected in real time, with advanced threat protection active across every category of known and emerging risk. Cloud application usage is fully governed, shadow IT has been eliminated, and the organisation has complete visibility into what is moving across its network. What Securze delivered was not just a technology deployment, it was a shift from an organisation that was reactive about security to one that is fundamentally, structurally protected.
