Top 10 Blockchain Security and Smart Contract Audit Companies

2

We rank the top 10 performing blockchain security firms offering services such as smart contract audits, blockchain security analysis, penetration testing, formal verification, and security audits. Security audits are extremely important – this year we’re seeing the rise of Decentralized Finance (DeFi)— a new application of decentralized Blockchain technology that is poised to replace the trillion dollars Global Finance industry. However, recent events such as the dForce hack have shown us that hackers can exploit weaknesses in smart contracts and steal money. It’s almost like robbing a bank, except in this case the bank is flush with crypto AND can’t defend itself. In the case with dForce, the hacker stole $25,000,000 USD (talk about a good haul) and with crypto transactions, we know this is not reversible.

Consequently, security solutions, tailored to the volatile nature of blockchain technology and its components, have started making moves to isolate and neutralize security threats common in the blockchain terrain. In this article, I will highlight and explore the workings of the top companies in the blockchain security niche.

It is therefore extremely important for security audits of projects, exchanges and blockchains to be done. Users must also know what security tests have been performed and if any red flags were raised.

Hacken

Hacken performs a wide range of security services for its clients. These suites of services include blockchain security consulting, web/mobile penetration testing, coordination of bug bounty programs, crypto exchange ratings, among other things.

The company has built a commendable reputation as a security risk assessment for companies requiring a digital environment to create or enable services for their consumers.

Hence, it comes as no surprise that Hacken has provided security services for non-blockchain giants like Air Asia. Furthermore, it has proven its commitment to blockchain technology by sponsoring and engaging security experts worldwide in security meetups.

Hacken has also created the HackenAI security platform designed to protect the end user from security risks and account compromises. Key features such as Darknet monitoring immediately alerts users of compromised passwords and possible darknet attacks. HackenAI is available on Android and Iphone devices.
