"With Castle, we've made account takeover a non-issue," shares Steven Ou, Chief Technology Officer at Touch of Modern, a leading e-commerce platform with over 14 million users, dedicated to unique and modern products.Visit site
In the face of an escalating security landscape with increased brute-force attacks and high-profile breaches, Touch of Modern realized a strong need for a robust solution. "As we saw more and more attacks, it became too burdensome to handle manually," Ou acknowledges.
The integration of Castle, with its real-time detection and mitigation of account takeovers, significantly transformed Touch of Modern's security approach, automating the prevention and creating an effective barrier against cyber threats. "At first, we just wanted to know when an attack was happening in real time. Castle made it possible to automate account takeover prevention, freeing up valuable resources," Ou explains.
Now, with Castle's proactive security measures and sophisticated detection capabilities, Touch of Modern is empowered to stay ahead of potential threats, reinforcing their commitment to user security. “The benefit of Castle is that account takeover is a total non-issue now. We’ve been able to do everything else we’d choose to prioritize. Castle has been instrumental in this evolution, reducing the risk and worry of potential ATO threats,” Ou affirms.

Recognizing the increasing trend of online threats and account takeovers (ATOs), Rue La La realized the need for a robust, user-centric solution. “For any e-commerce provider, potential fraudulent activity and cybercriminals are part of the reality of the industry now," Pickering acknowledges.
The introduction of Castle, with its machine learning capabilities focused on preventing ATOs, significantly transformed Rue La La's security approach. Moreover, it optimized their operations. The tool automated the monitoring of suspicious account activities, reduced manual work, and allowed the engineering team to focus on their core functions. “A successful integration is one that I don’t have to sit on to use and that can alert us with a minimal amount of false positives," Pickering explains.
Now, Castle's proactive security measures and next-gen heuristic have empowered Rue La La to stay ahead of potential threats, reinforcing their mission of putting members first. “Castle has been a great partner, and has made it possible for our security and engineering teams to continue to focus on innovation rather than potential ATO threats,” Pickering affirms.

Confronting the relentless issue of spam and copyrighted content being published on their site, leading to an unbearable amount of DMCA reports per week, GitBook recognized the urgent need for an efficient solution.

Castle not only made this possible but also allowed us to automate the entire process, thus freeing up significant resources," Remi elucidates.
Now, with Castle's proactive security measures and flexible detection capabilities, GitBook is well-equipped to stay one step ahead of potential threats, reinforcing their commitment to content integrity. "The advantage of Castle is that dealing with malicious content is now practically a non-issue. We've been able to focus on other vital priorities.
