Sentry
With the rise of “AI” and most mainstream solutions being either too complex for end users to use or ineffective, we decided to develop our own solution to the problem. This solution doesn’t help train models or mine your users’ data.
Our unobtrusive solution provides several options to secure your site. These include a novel CAPTCHA, emaled or text to mobile pin verification - provided via our documented and open API, making it easy for anyone to integrate it with their application.
We even provide a plugin for WordPress, and a plugin for Redmine so you can install it without coding. You can also reach out and request for an integration, we'd be happy to discuss your needs.
Overview
Our solution is designed to provide a simple way to make it easy for humans and challenging for bots to access your site. The initial offering comprises a simple CAPTCHA image challenge and a more effective interactive challenge. We have plans to expand on this with an accessible alternative option available soon.
The API is very simple to install, requiring a simple script include, some markup where you want the challenge to appear, and a simple confirmation check on the server side. If you are a WordPress user, the plugin simplifies this substantially. Our aim is to enhance security by implementing a straightforward CAPTCHA mechanism, effectively filtering out non-human users attempting to access.
Is this foolproof?
We provide three alternatives to secure your site, and while we do not claim to be foolproof, we do aim to make it as difficult as possible for bots to access your site. The CAPTCHA is designed to be simple for humans to solve, but challenging for bots.
In the paid option we also offer alternative methods of verification, such as email and text message verification, which can be used to further secure your site. These methods are designed to be user-friendly while still providing a robust level of security.
With the advent of artificial intelligence a basic CAPTCHA may not be sufficient to deter sophisticated bots, our premium CAPTCHA option is designed to further enhance security. It is designed to be even more challenging for bots to solve, while still being user-friendly for humans. This option is available as a pay-as-you-go service, where you are only charged for successful submissions.
While it is not feasible to guarantee complete protection against automated attacks, our goal is to make the process as challenging as possible while maintaining simplicity for users. The service is not limited to a single type of puzzle or challenge, and we employ additional metrics, such as the visitor’s location and solving speed, to further profile potential actors.
Ultimately we aim to provide a solution that is effective against the majority of automated attacks, while still being user-friendly for legitimate users. We are committed to continuously improving our service and adapting to new threats as they arise.
Privacy first
Our plugin prioritises user privacy. We will not utilise your visitors to train AI models or record any information beyond what is essential to verify the legitimacy of your users. Furthermore, we will not share any data collected during this process with third parties.
How does it work?
This plugin works by requesting a CAPTCHA to be generated by our cloud service. This CAPTCHA is delivered to your site with some encrypted data. When a user attempts to solve the CAPTCHA, the service uses this data to validate their response. The plugin then passes or fails the action, thereby protecting your site. We additionally check request headers, IP addresses, and some other traits to detect if the visitor is a person. Currently, a visual CAPTCHA is used; however, we are going to further develop the solution and are committed to finding innovative and simple ways to validate your visitors as being human or not.
The API means any form submission can be protected; the WordPress Plugin is configurable too and can be configured to protect: forms, comments, and logins.
Pricing
While we do provide a free version, which offers basic protection with simple image CAPTCHA, unlike the pay-for version - these can be solved in seconds using AI. If you want more comprehensive protection, then we also offer a pay-as-you-go enhanced version in which we make a tiny charge for each successful login or submission; we believe this is the fairest way to charge as it encourages us to deal with the issue in an efficient way. We do not charge to block spam! The premium version offers additional features and capabilities to further enhance your site's security - such as email and text message verification.
As of the time of writing, the pricing is as follows:
| Feature | Description | Price |
|---|---|---|
| Basic CAPTCHA | Simple image challenge, easy for humans, basic bot protection | Free |
| Enhanced CAPTCHA | More advanced, interactive challenge, harder for bots | 1 Credit per solve |
| Email Verification | Send a code to user’s email for extra verification | 1 Credit per solve |
| SMS Verification | Send a code to user’s mobile for extra verification | 5 Credits per solve |
1 Credit can be as low as 1p, depending on your subscription tier, and you can top-up as needed. Subscription tiers include a generous monthly provision, and you can use the credits across all your sites and services. When your credits run low, you can top-up as needed, or you can subscribe to a higher tier for more credits.
If you run out of credit and you have not subscribed, the service will continue to work, but you will not be able to use the enhanced features until you top-up or subscribe.
