The 3 Silent Cyber Risks Most Boards Still Underestimate

By Sanjiv Cherian - Microminder Cyber Security, 

The prevalent perception among boards today is that they possess a decent idea of cyber risk. Dashboards are discussed and investments are accepted, and security leaders update regularly. At face value, it seems that cybersecurity has already found its niche in the boardroom.

However, in the real sense, a gaping hole exists.

The visibly risky nature of ransomware headlines, regulatory compliance, and high-profile breaches often take up time with boards. In the meantime, the most threatening threats are silently brewing just under the surface, within the business operations, partnerships and business decision making structures.

These are what I term silent cyber risks and tend to be the most damaging.

Why Silent Risks Matter More Than Ever

Silent risks are not obvious. They rarely trigger immediate alarms, and they are difficult to quantify using traditional metrics. Yet, they create systemic vulnerabilities that accumulate over time.

Unlike conventional threats, these risks:

  • Bypass traditional detection mechanisms

  • Sit outside standard reporting frameworks

  • Escalate without clear visibility

In my work across industries and regions, I have consistently observed that while organizations invest heavily in cybersecurity, they often overlook these foundational exposures.

Let me highlight three such risks that boards continue to underestimate.

1. Third-Party and Supply Chain Exposure

Modern enterprises are no longer standalone entities. They are ecosystems, deeply interconnected with vendors, partners, and service providers.

This interconnectedness creates a fundamental challenge:
 your security is only as strong as your weakest partner.

Organizations today rely on:

  • Cloud providers

  • SaaS platforms

  • Managed service vendors

  • Global supply chain networks

Yet, visibility into the security posture of these third parties remains limited.

Many boards assume that vendor risk is being managed through compliance checklists or contractual obligations. In reality, these measures often provide a false sense of assurance.

We have seen multiple incidents where breaches originated not within the organization, but through trusted external partners.

The core issue is this:
 You can outsource operations, but not risk.

What should change:

  • Move from periodic assessments to continuous monitoring

  • Classify vendors based on risk impact, not just function

  • Elevate third-party risk to a board-level discussion

2. AI-Driven Threat Acceleration

Artificial Intelligence is transforming business at an unprecedented pace. But while organizations focus on AI as a driver of efficiency and innovation, attackers are leveraging it as a force multiplier.

Cyber threats are no longer manual or slow. They are:

  • Automated

  • Scalable

  • Increasingly intelligent

We are already seeing:

  • AI-generated phishing campaigns that are highly personalized

  • Deepfake-based fraud targeting executives

  • Automated vulnerability discovery and exploitation

The result is a widening gap between attacker capability and organizational response speed.

Many boards underestimate this risk because AI is still viewed primarily through a business or innovation lens. The security implications are often secondary or misunderstood.

But the reality is clear:
 AI is not just transforming business, it is transforming the threat landscape even faster.

What should change:

  • Integrate AI into cybersecurity defense strategies

  • Build awareness of AI-driven risks at the leadership level

  • Conduct scenario planning for AI-enabled attacks

3. Cyber Resilience Gaps

For years, cybersecurity strategies have been built around prevention, keeping attackers out.

That model no longer holds.

The question is not if an organization will experience a breach, but when. And more importantly, how well it can respond and recover.

Unfortunately, many organizations remain underprepared in this area.

Common gaps include:

  • Incomplete incident response plans

  • Limited crisis communication readiness

  • Lack of alignment between IT, security, and business functions

  • Undefined recovery time expectations

Boards often underestimate this risk because of a simple assumption:
 “We haven’t experienced a major breach yet.”

But absence of evidence is not evidence of absence.

The real impact of cyber incidents today is not just data loss, it is business disruption:

  • Operational downtime

  • Revenue loss

  • Reputational damage

This is why I often emphasize:
 Cybersecurity is no longer about keeping attackers out, it’s about staying operational when they get in.

What should change:

  • Conduct regular simulation exercises (including board participation)

  • Measure resilience through recovery metrics, not just prevention metrics

  • Align cybersecurity with broader business continuity strategies

Connecting the Dots

What makes these risks particularly dangerous is their invisibility.

They do not always appear in standard reports. They are not easily captured in KPIs. And they often sit at the intersection of technology, operations, and strategy.

Yet, they have one thing in common:
 they significantly increase organizational exposure.

As I often discuss in the context of Sanjiv Cherian Business perspectives, cybersecurity is no longer a technical domain, it is a core business discipline. Understanding these silent risks requires a shift in mindset, not just tools or budgets.

The absence of visibility does not mean the absence of risk.

Final Thoughts

Boards have made significant progress in recognizing the importance of cybersecurity. But the next step is deeper and more nuanced.

It requires:

  • Expanding the definition of cyber risk

  • Looking beyond the obvious threats

  • Embedding cybersecurity into strategic decision-making

The most impactful risks today are not the ones making headlines. They are the ones quietly shaping your organization’s resilience, exposure, and long-term stability.

If you know about Sanjiv Cherian and  work with organizations globally, true cybersecurity leadership is not about reacting to threats. It is about anticipating what others are not yet seeing.

The question is not whether these silent risks exist.

The question is, are you prepared to recognize them, and act before they become visible?

Machine Identities Are Now Your Largest Insider Threat — A Practical Business Perspective

By Sanjiv Cherian I have witnessed in the recent years a reliance on technology by businesses as never before. Operations have been streamlined to be faster and efficient through automation, cloud platforms, APIs, and connected systems. However, with these advantages, a novel form of risk has quietly come to the fore, a risk that most organizations under-estimate. Machine identities is that risk . When the term insider threat is mentioned to most individuals, they tend to have in mind the employees or contractors. Nevertheless, in the digital world today, machines themselves (applications, bots, automated services) can be equally risky when not handled correctly. These machine identities have surpassed human users in several contemporary organizations and in some cases, by a large margin. As my experience working in the sphere of technology-based projects and digital ecosystems demonstrates, it is a shift that every sanjiv cherian business leader must listen to. It is not fear, it is ...

The Importance of Cybersecurity in Business Growth

  By Sanjiv Cherian In the modern landscape, business growth and technology are no longer two separate lanes, they are the same road. As an entrepreneur, I’ve watched the digital landscape evolve from a supportive tool into the very backbone of how we create value. However, with this massive expansion of opportunity comes an equally massive expansion of risk. I’ve always viewed protection and progress as two sides of the same coin. If you look into the mission statement found in About Sanjiv Cherian , you’ll see a recurring theme: resilience. To me, cybersecurity isn’t a barrier to speed; it’s the foundation that allows a business to scale without the constant fear of a catastrophic setback. In my view, it’s actually the opposite of a delay, think of it like the brakes on a high-performance race car: they aren't there to make you go slow; they are there so you have the confidence to go fast. Today, cybersecurity for business growth is a fundamental enabler that allows organizati...
