An engineering firm. Not an agency.
Since 2014, Mobisec has been the team operators reach for when the system actually has to work. Manufacturing ERPs that move containers across continents. Telecom platforms that stay up when a million subscribers need them. Consumer applications that survive real-world retention in competitive markets.
A decade of building systems that had to work.
We've spent the last ten years in three domains most firms treat as unrelated: carrier-scale telecom, export-grade manufacturing, and competitive consumer apps. The cross-pollination is the point.
Mobisec founded in Colombo
Established with a focus on building software infrastructure rather than packaged products, engineering for operators who needed their systems to work at scale.
Deep telecom integrations
Began multi-year engagements with Sri Lanka's major telecom operators, building and operating VAS platforms that today sustain 10,000+ SMS/sec.
Australian consumer market
Expanded into consumer mobile applications for the Australian market, where retention and ASO discipline became a second core competency.
End-to-end manufacturing ERPs
Delivered the Help Grow Lanka platform, a dual-system ecosystem that doubled production throughput for a global coco-peat exporter.
Senior on the keys.
The leaders you meet in discovery are the leaders writing the architecture in week one. No bait-and-switch between consultants and delivery.

Nalin Uthurawala
AdvisorFounder of Dedunu Fibre Mills, Help Grow Lanka, and several Sri Lankan enterprises. Award-winning entrepreneur with decades of leadership in agricultural exports and manufacturing. Advises Mobisec on enterprise operations and manufacturing domain strategy.
Disclosure. Nalin is a client as well as an advisor: Help Grow Lanka runs the ERP platform we built. His advisory role covers manufacturing and export operations. He has no access to any other client's system, environment or data.
We work with more than one exporter. Here's how we keep that safe.
Coco peat and coir is a small industry. Any software partner with real depth in it will have worked with someone you compete with. We would rather say that plainly than have you find out later.
Confidentiality by default
We sign an NDA before discovery, not after. Everyone at Mobisec who touches a client system is bound by confidentiality terms in their own agreement with us.
Separate systems, not shared ones
Each client runs in their own hosting environment, provisioned under their own cloud account. Your data never sits in a shared instance alongside another client's, and it stays under your ownership and billing, not ours.
Nothing is published without your approval
We would like to write about the work. But no case study, metric, screenshot or client name goes public until you have read it and approved it in writing.
Your processes are yours
Your costing model, supplier terms, grading parameters and buyer relationships are your competitive advantage, not reusable material. We build to your process; we don't carry it to the next client.
Principles we engineer by.
Build, don't assemble
We're a software engineering firm, not a systems integrator. When the problem is real complexity, we build the system, because no off-the-shelf package will fit.
Operate, don't just ship
Our telco platforms have been running under our watch for seven years. We stay engaged past launch because the interesting engineering problems only show up after release.
Measure the right thing
Downloads aren't retention. Uptime isn't resilience. Features aren't adoption. We choose the metric that actually matters, and we're honest when it moves in the wrong direction.
Senior on the keys
The engineer you meet in discovery is the engineer writing code in week one. We don't bait with senior consultants and deliver with juniors.
Engineered in Sri Lanka. Deployed globally.
From Colombo to Sydney, our systems run in production for enterprises, telecom operators, and consumer audiences.
Telecom VAS, enterprise ERP, and manufacturing supply chain engineering.
Consumer app portfolio sustaining 200,000+ monthly active users in utility and lifestyle categories.
Building something that has to work at scale?
Whether it's an ERP that can't afford a week of downtime, a consumer app entering a saturated market, or a telco platform that needs to hold five nines, talk to our engineering leadership directly.
