ATO – Account Takeover Attacks – is still one of the top cybersecurity threats in 2025. Just last year, for example, account takeover cases in the US went up 13% and multi-accounting is up 10% year over year.
Right now, one in three attacks uses AI in some way, and as the attackers get smarter, so must we. Below we’ll walk through 8 account takeover security providers with a quick summary of what makes them great. But before we get into that, let’s define what ATO security looks like.
What is Account Takeover Security?
ATO security refers to the systems, tools and strategies to detect and prevent unauthorized access to user accounts. These attacks happen when cybercriminals get hold of login credentials – whether through phishing, brute force or data breaches – and then use those credentials to impersonate legitimate users.
Once inside, attackers can steal sensitive data or use accounts to further infiltrate, that’s why you need a defence mechanism in place. The providers we’re going to talk about cover a range of bases, from risk scoring to bot management, to stop account compromises before they happen.
When it comes to bot management, specifically, this is one of the most important bits to consider. Just recently a report showed that over 70% of web traffic is automated bot traffic, ATO attacks are a big part of that and so finding a provider that detects and neutralizes bot automation has gone from being an optional feature to a necessity.
Datadome
Datadome is one of the best solutions for this. Globally recognised for its AI-powered bot and fraud detection technology, it can detect suspicious behaviour in real time using advanced machine learning to stop attacks before they hit users.
Plus it’s for both startups and large enterprises, with Datadome Account Protect offering automated risk scoring, behavioural analysis, anomaly detection and CDNs and WAFs integration, plus API and web app coverage.
Imperva
Imperva is another well known provider, bot detection with ease of end user experience. Its biggest strength is that cybersecurity isn’t a chore for real customers.
With simple user onboarding, Imperva protects accounts from takeover attempts with zero friction, so businesses can stop attacks before they scale and keep a smooth and trustworthy experience for their customers.
Telesign
Telesign is also highly rated in 2025 for its communication driven approach. By using SMS, phone verification and identity intelligence it ensures users logging into accounts are who they say they are, adding an extra layer of authentication that’s hard for attackers to bypass.
Phone verification is one of its main features but like Imperva it’s also notable for no friction and seamless user experience, which is important for companies that need to find that balance.
Akamal
Akamal has an edge when it comes to global content delivery and edge computing – literally one of the biggest in the world. Which makes it a top choice for companies looking to protect lots of accounts at the same time, while also making sure people can get fast and reliable access to services from all around the globe.
As for what Akamal can do in terms of security, the company uses edge-based security measures to help reduce latency and still be able to monitor lots of traffic at once. It does this with the help of AI linked to behavioural analysis and risk-based scoring to block any dodgy log in attempts.
Unlike a few of the other options we’ve mentioned, Akamal does come with a slightly higher price tag, and setting it up can be a bit more complicated than some other solutions – especially for small businesses looking for something a bit more straightforward. But keeping the earlier cybersecurity statistics in mind –and the evolving threats that businesses are facing – this could be a small price to pay for global visibility.
Darktrace
Another provider that leverages self-learning artificial intelligence is Darktrace, which offers unique real-time defence across numerous digital environments. Unlike a lot of the other security tools out there, it learns from your business and uses that to respond to any would be attackers. Plus, with continous detection, Darktrace can pick up on threats long before you’ve even seen them before.
Radware
Lots of e-commerce and banking companies are a big fan of Radware and use it to help keep their apps and websites safe from bots and other malicious traffic. Part of the reason they like it is because of its super effective bot detection system, which gives security teams a really clear view of any login attempts that might be dodgy.
Having a good dashboard is basically a must for any security team, and for Radware, that’s exactly what its analytics dashboards do. It gives you a real-time view of whats going on so you can quickly spot any threats and take action before its too late. The downside is that Radware is a bit on the pricier side, but if you’re in e-commerce business or fintech, it might just be worth the extra cash.
Proofpoint
When it comes to phishing incidents, Proofpoint is one of the first things that springs to mind. It uses layered defence and contextual intelligence to help track down high risk users, and even flags up any suspicious emails before they become a problem. Plus with tight integrations with email security, Proofpoint makes it easy to keep all your accounts safe from phishing attacks.
F5
Last but not least there’s F5, which specialises in helping keep customer experiences running smoothly – even when your systems are under attack. Their distributed cloud bot defence system is designed for big businesses that need to keep all of their digital experiences secure.
Like all of the other options on this list, F5 is all about helping stop malicious activity before it can cause any problems, and keeping genuine users from getting caught in the crossfire. The main thing to keep in mind is, you want to make sure your customers are having a good experience, and not getting frustrated by slow or crashed services.
