@Charley | Charlemagne Labs

in an era with AI benefit and AI horror stories both saturating, Charley is one of the few that seem to grasp the first principles of security. I spend my days researching quantum resistant encryption and advising on IAM challenges. The true weakest link is also that factors are not phishing resistant. On-device prevention of social engineering is by far the most valuable and efficient defense layer. Excited to see Agent Charley in action

@Claude

The most humanly AI i have used so far but the problem is as soon as you start piling up messages in single chat session , it starts getting slow and at some point it starts freezing and also uses a lot of resources. For time being its okay to do 3 4 messages but as soon as we continue it has messages limitation and also starts getting very very slow . For the price of £18 per month this is unacceptable and with the newly introduced feature called project, if we start new chat within the project we cannot continue with the context we provided in other chats within same project. There are lot of improvements for them to work on. And to start with the its speed and its price

GPT 5.5

By OpenAI

GPT-5.5 is OpenAI’s newest flagship model for real work on a computer. It is built for stronger agentic coding, computer use, knowledge work, and early scientific research, while matching GPT-5.4’s per-token latency in real-world serving and using fewer tokens to complete the same Codex tasks.

We’ve been using ZeroThreat.ai to help foster a better security culture among our engineers. Because the Web App Security Testing provides such clear evidence of vulnerabilities, we use the reports as teaching tools during our code reviews. Developers can see exactly how an attacker would exploit their code, which has led to a noticeable improvement in the quality of the code they write. It’s stopped security from being a "last minute" problem and made it part of our everyday culture. Really happy with how it’s changed our workflow.

In the public sector, we don't always have a dedicated "security researcher" on staff. We needed something thorough but not overly complex to manage. The Automated Penetration Testing from ZeroThreat.ai was exactly what we needed because the setup was quick and didn't take much effort. We were running scans in minutes, and the dashboard is clear enough for my IT guys to understand. It helped us identify some misconfigured SSL stuff and a few leaked keys we didn't know were exposed. It gives us a lot of peace of mind without being a headache to run.

ZeroThreat has been a true game-changer for our team. As someone who cares deeply about keeping our retail platform secure, I love how ZeroThreat quietly works behind the scenes, spotting and blocking threats before they become issues—without requiring constant monitoring or technical know-how. The alerts are simple to understand, actionable, and extremely reliable—no more chasing false alarms. Since integrating ZeroThreat, we've seen a noticeable drop in suspicious activity, and I wake up each day knowing our APIs are well-protected. It makes security effortless and gives our whole team peace of mind.
