The question on every InfoSec professional's mind today is, "How can you protect your organization's assets against the inevitability of data breaches while maintaining business continuity and minimizing risk?" To do this, you need a shield against cyber attacks that protects your organization externally and internally. That shield is a robust Information Security Management System (ISMS) that provides airtight policies and procedures to keep your company's data safe from hackers, leaks, and other digital threats.
The threats are real, and each day, more news breaks of significant breaches affecting companies as diverse as MGM, MOVEit, PharMerica, and Twitter (X). It's why 51% of organizations boost their security spending after experiencing a breach. They're putting money into ISMS elements like better incident response plans, training employees on security, and getting advanced tools for spotting and dealing with threats.
However, an ISMS is a machine with many moving parts, especially in larger companies. For your organizational information security to reach a desired level of consistent excellence, you need to rely on an international standard for ISMS management: ISO 27001. Compliance with ISO 27001 is a surefire way to set up your ISMS according to current best practices for safeguarding information and cybersecurity assets.
Here's everything you need to know about implementing ISO 27001 and passing a compliance audit.
