Built-In Security for Browser Extension Development
Each extension we build ensures enterprise-grade data protection, integrity, and user control.
Minimal and controlled access
Apply least-privilege principles by requesting only essential permissions and restricting access to specific domains, tabs, and browser contexts.
Secure authentication and user roles
Implement SSO, token-based authentication, and role-based access control to ensure users interact only with authorized data and actions.
Safe data handling
Control how data is captured, processed, and transmitted by limiting collection, protecting sensitive inputs, and enforcing strict data flow rules.
Compliance-aware workflows
Embed compliance checks directly into user actions, including DLP controls, phishing detection, domain validation, and risk alerts.
Dependency and code security
Audit third-party libraries and extension components to eliminate vulnerabilities and prevent unsafe code execution within the browser.
Secure deployment and auditability
Enable secure distribution via browser stores or enterprise channels with version control, update governance, and logging of critical actions.

Emerline is an important part of our strategic team!
Emerline has been our technology partner since late 2012. In the early years I thought that would be a short-term gap fill until I could afford to hire my own technical team in the US. But they have consistently met the demands of our growing company and helped us build what we believe is the industry's best solution option. Emerline provides high quality work, so much so that our platform's reliability and accuracy has been mentioned by our largest customer's internal vendor survey repeatedly. The individuals we work with aren't just contractors, they are an important part of our strategic Team and we enjoy working with them every day!

My experience with Emerline has been great
The team was hired to design and develop the Echospectra mobile and web applications, as well as to integrate them with a variety of cloud services. A critical requirement was to rapidly develop the apps in an agile manner, quickly implementing important stakeholder and user feedback as it came along, and fixing any outstanding bugs. The team managed to accommodate this kind of agile, change-driven process successfully. Thanks to their rapid development approach, we've been able to build the initial app versions and then continuously iterate on them to refine our product offering and make sure it meets and exceeds customer expectations. I highly recommend them to anyone looking for a reliable partner who delivers on time and on budget.
