Rein is officially on the @Google Marketplace.
Which means:
1. Virtual tea party.
2. You can now deploy Rein even easier to secure your most business-critical agents.
You probably care more about #2.

Your AI agents arenโt doing what you think theyโre doing.
Netanel Rubin, our Co-founder and CTO, breaks down how to uncover what your MCPs and agents actually do behind closed doors, AFTER a prompt is sent.
Unlike most AppSec tools, we value silence.
If thereโs nothing to stress about, youโll hear nothing from Rein.
Real value is staying quiet โ and only alerting you when something is actually important.
Have a quiet, alertless weekend.
Thank you @kevtownsend for this feature about us on SecurityWeek.
Our favorite part has to be this - "Securing production applications from the inside โ Rein Security offers a new approach to application security."
We're humbled.

Today, Rein launches to bring reality to AppSec.
AppSec didnโt need another tool.
It needed context.
No more guessing how apps behave.
No more proxies.
No more assumptions.
Reality, finally.
