Blockchain<\/a> is widely regarded as a powerful tool for financial, legal, and a wide range of other business applications. But what about security? Is it possible that the same technology that can be used to protect transactions on an open digital ledger can also protect data<\/a> and infrastructure<\/a>?<\/p>\n

And what\u2019s more, it can reimagine the entire security regimen that has evolved over the past decade, quite probably making the complex and expensive security ecosystems at most enterprises \u2013 from firewalls and monitoring platforms to antivirus software<\/a> \u2013 obsolete.<\/p>\n

Despite more than $1 trillion in spending on traditional security measures over the past five years alone, hackers<\/a> are still exploiting known and unknown vulnerabilities to gain access to private data and systems \u2013 primarily by intercepting device, application, and network communications.<\/p>\n

Blockchain reduces these vulnerabilities in a number of ways:<\/p>\n
