Why GetThru uses Paraxial.io

Matt Silbernagel, 2025-06-09

At GetThru, we use Elixir to build peer-to-peer communication tools that help mission-driven organizations connect with people at scale. Our clients, ranging from advocacy groups to educational institutions, trust us to take security seriously, which we are committed to do.

That’s why we use Paraxial.io. It’s helped us improve our security posture, reduce engineering overhead, and meet the rigorous expectations of our customers, without getting in the way.

Security Designed for Elixir

We’ve built our infrastructure on Elixir because of its scalability, reliability, and fault-tolerance. But that choice also created a challenge: most security tools simply don’t understand how BEAM-based applications operate.

Paraxial.io is different. It’s designed from the ground up for the Elixir ecosystem, offering deep introspection into processes and run-time behavior. That means it catches things generic security tools often miss - because it knows how Elixir applications actually work.

This BEAM-native insight is a key reason we use Paraxial.io. It’s not a bolt-on solution, instead it fits seamlessly into our application.


Paraxial.io gives us real-time visibility into potentially malicious behavior inside our production systems, from unexpected code execution to anomalous process activity. This added layer of protection helps us stay ahead of threats and keeps our customers’ data safe and secure.

Engineers Focus on Building

Before Paraxial.io, our engineers had to manually sift through logs and metrics to anticipate attacks. It was time-consuming and reactive.

Now, Paraxial.io handles that burden. It gives us smart, focused alerts so we only get notified when something important happens and proactively blocks traffic from malicious actors so the engineers can stay focused on delivering new features and innovations instead of playing defense.

Checks the Boxes That Matter

Working with large organizations means answering detailed security questionnaires and surveys. Paraxial.io helps us confidently say yes to many of the critical questions around runtime monitoring, intrusion detection, and proactive alerting. It’s a major asset in client security reviews.

Built for Customization

Every application faces unique threats, and we needed a solution that could adapt to our specific risk profile. Paraxial.io makes it easy to write and adjust custom rules allowing us to tailor our protection to match real-world threats.

A Great Team Behind the Product

Working with the Paraxial.io team has been a highlight. They bring deep expertise in both Elixir and security and they’ve been incredibly responsive and collaborative throughout the process. They don’t just offer a product; they help us strengthen our security approach in a way that makes sense for our stack.

Paraxial.io gives us powerful, Elixir-native runtime security that protects our users, empowers our engineers, and checks critical compliance boxes all without slowing us down. And with a knowledgeable, supportive team behind it, it’s become a key part of our infrastructure.

If you’re running Elixir in production, Paraxial.io is the security tool you’ve been waiting for.
