<h2>Thorn's mission</h2>
<h2>Thorn defends children</h2>

<p>
Thorn builds technology to defend children from sexual abuse. Their work focuses on finding victims
of child sex trafficking faster, and eliminating child sexual abuse from the internet.Thorn partners
with tech companies, law enforcement, as well as other NGOs, to build products that provide the
front lines with the latest technology to find the most vulnerable child victims faster.
</p>
<p>
Thorn’s life changing work and not-for-profit status made it a simple decision to provide
Sourcegraph’s enterprise features free of charge. For many children, Thorn plays a critical role in
speeding up the time it takes for them to be identified and we’re proud to be supporting them with
their mission.

child victims faster. Thorn software reduces the time to identify many children.

<h2 class="pt-5 pb-1">Sunsetting deprecated systems was costly and risked production stability</h2>
<p>
As Thorn’s products evolved, it became difficult to trace the impact of code changes to core
application components, as it was difficult to determine what code might rely on legacy
architecture, risking instability and greatly increasing the demand on development and review.
Determining which code relied on legacy architecture was difficult. Developers took too long to
ensure that changes to legacy systems didn’t affect production stability.

<p>
Over 9,000 officers in 38 countries rely on Thorn’s systems to identify child victims of sexual
abuse. Any downtime of these services has a negative impact on Thorn’s ability to identify children
globally.

<h2 class="pt-5 pb-1">Existing tooling was not sufficient</h2>

<p>
Tech debt, and the upkeep of legacy code was becoming increasingly problematic. Previous attempts,
such as cloning all repositories locally and using grep to find references, were inadequate,
especially when considering simultaneous development by multiple teams across many different
projects, repositories, and branches. It was costly to determine if all the different microservices
were properly in sync when removing legacy application code.

Sourcegraph code search gave Thorn the ability to find references to deprecated systems. But more
importantly, it proved itself to be an invaluable new part of their code review process.

<InContentBlockquote quote="In pull requests, team members would include links to Sourcegraph code search, in order to prove all references to a deprecated system had been removed. This gave the reviewer confidence that the code was safe to merge." />
<p>Sourcegraph is now essential to their code review process. </p>

<h2 class="pt-5 pb-1">As a result, deprecated systems were taken offline without downtime.</h2>
<p>
Thorn’s developers could then systematically remove or modify deprecated systems, removing huge
amounts of tech debt in the process. This benefited all areas of the architecture, including not
only application code, but also build, deployment, logging, and monitoring systems—any tool that
supported the deployment and uptime of the application.

<strong>
Sourcegraph’s code search enables developers and DevOps teams to find dead code, unused
packages, and references to deprecated systems, organization wide across tens of thousands of
repositories.

Being able to take advantage of industry leading solutions like Sourcegraph provides critical
support to Thorn’s mission. Every start-up has to make choices about when to rebuild their systems
and when to move forward accruing technical debt, Thorn is no different, but here at Sourcegraph,
we’re proud that our tools could be used to make the Thorn team a little more successful, a little
faster.
