Why Small and Medium-sized Businesses Should Conduct Annual Vendor Review
By Rob Ashcraft, CISO at KeyStone Solutions
Small and medium-sized businesses (SMBs) increasingly rely on third-party vendors for critical services such as IT support, cloud hosting, and financial management. While these services enable efficiency and scalability, they also introduce significant risks. A single vulnerability in a vendor’s environment can cascade into a full-blown breach for your business, disrupting operations and damaging customer trust. Annual vendor reviews provide SMBs with a structured approach to identify and mitigate these risks before they escalate, ensuring business continuity and resilience.
What Does This Mean for Your Business?
Commentary by KeyStone’s Rob Ashcraft
An article on ISACA explores how Multi-Factor Authentication (MFA) is evolving from a basic security measure into a cornerstone of modern cyber defense strategies. It highlights the growing sophistication of cyberattacks and how traditional password-based systems are no longer sufficient to protect sensitive data. MFA, by requiring multiple layers of identity verification, significantly reduces the risk of unauthorized access and mitigates common attack vectors such as phishing and credential theft.
Additionally, the article fairly points out that MFA adoption is not without challenges. Organizations must balance security with user experience, address integration complexities, and prepare for emerging threats like MFA fatigue attacks. The article concludes that MFA will play a critical role in shaping cybersecurity frameworks in the 21st century, but its success depends on continuous innovation and alignment with broader zero-trust principles.
Key takeaways:
-
- MFA is transitioning from an optional security feature to a fundamental component of cyber defense
- Traditional password-only systems are increasingly vulnerable to sophisticated attacks
- MFA significantly reduces risks associated with phishing and credential compromise
- Challenges include user friction, integration hurdles, and new attack methods like MFA fatigue
- Future MFA strategies will align closely with zero-trust architecture and adaptive authentication
