Yana Ifraimov
NOC Engineer @Skai
"Advice: purchase both and read them end to end. At first they seem very topical and tied to a single family of vulnerabilities each, but Liran does amazing job at going deep, showing variety of real world exploits, how to remediate and code defensively better. 10/10 recommend"
Aranđel Šarenac
12+ years developer, focusing on Identity Security
"Node.js security rock-star Liran Tal drops another book on how to ship safe Node.js applications. I know it's hard to tell sometimes where to start from when it comes to security, as the internet is flooded with content. Well, look no more - trust content composed by Liran"
Gal Weizman
Browser JS Application Security at MetaMask & LavaMoat
"It's not every day that you can pay less than $20 for years of security wisdom. Just got this and will be using the book during my streams to improve my code."
Ray Fernando
