“Can we ever become 100% secure?”

It’s a common question from organizations looking to protect their data and systems. While the desire for absolute security is understandable, the short answer is no—achieving 100% security is not possible. And that’s okay.

Here’s why absolute security isn’t realistic, why we aim for a balance between security and usability, and how standards like ISO 27001 guide organizations toward a more practical, risk-based approach.

Why 100% security is impossible

  1. Human error
    Whether it’s clicking on a phishing link, using weak passwords, or forgetting to apply security patches, human mistakes create vulnerabilities that no technology can completely eliminate.
  2. Interconnected systems
    Today’s digital world is built on interconnected systems. From cloud services to third-party integrations, your organization’s data is rarely confined to a single secure location. This connectivity increases the attack surface, making total protection impossible.
  3. Evolving threats
    Cyber threats evolve constantly, with attackers using increasingly sophisticated techniques. Even with state-of-the-art defenses, new vulnerabilities can emerge faster than organizations can respond.
  4. Usability vs. security
    Striking the right balance between security and usability is critical. Overly restrictive measures can make systems difficult to use, leading employees to find workarounds that create new risks. For example, strict password policies might push users to write passwords on sticky notes—a clear security flaw.

The practical approach: risk management

Instead of aiming for unattainable perfection, organizations should focus on managing risks. This means identifying potential threats, assessing their impact, and implementing measures to reduce risks to acceptable levels.

ISO 27001 and the risk-based approach

ISO 27001, one of the leading standards for information security, emphasizes a risk-based approach to managing cybersecurity. Here’s how it works:

  1. Identify Risks: Regularly assess vulnerabilities in your systems, processes, and people.
  2. Implement Controls: Choose security measures that mitigate the most significant risks while maintaining usability.
  3. Monitor and Improve: Use the Deming Cycle (Plan-Do-Check-Act) to continuously evaluate and improve your security practices. Mistakes and incidents become learning opportunities.

This framework helps organizations focus their efforts where it matters most, rather than spreading resources thin in a futile attempt to eliminate all risks.

Striking the balance

The goal of cybersecurity isn’t perfection—it’s resilience. By striking a balance between protection and practicality, organizations can:

  • Reduce the likelihood of breaches
  • Minimize the impact of incidents
  • Maintain productivity and usability

Investing in tools like Guardian360’s managed security services can help you achieve this balance. From vulnerability management to compliance monitoring, our solutions are designed to enhance security without disrupting your operations.

The bottom line

Absolute security may be unattainable, but a strong, risk-based cybersecurity strategy can provide confidence and protection against most threats. By focusing on continuous improvement, learning from mistakes, and aligning with standards like ISO 27001, you can build a resilient organization that’s prepared for the ever-changing threat landscape.
