The Top 5 Threats Every CEO Should Lose Sleep Over
Over the past two years, decodingCyber's One2 Watch series has featured 20 of cybersecurity's most respected voices, from former FBI Special Agents to Fortune 500 CISOs, from self-taught experts to Silicon Valley veterans. Each brought decades of hard-won experience and unique perspectives on the threats keeping business leaders awake at night.
After analyzing hundreds of pages of insights from these conversations, five threats emerged as the most urgent concerns. These aren't theoretical risks; they're the clear and present dangers that could devastate your organization tomorrow if left unaddressed. And yes, even you, small businesses. In reality, you might be at the most risk.
What makes these threats particularly dangerous isn't just their potential for damage, but their ability to exploit the human element that one solution can fully protect. The experts we interviewed consistently emphasized that the most sophisticated attacks succeed not by breaking technology, but by breaking trust, process, and human judgment.
Here are the five threats that dominated our experts' nightmares, plus actionable advice they (and we) have curated to help you sleep better.
1. Unmanaged Cloud Sprawl
The Threat
Your organization's cloud infrastructure is growing faster than your ability to secure it, creating blind spots that attackers exploit with devastating efficiency. Cybersecurity expert Doran Blinderman identifies unmanaged cloud sprawl as the greatest threat facing organizations today.
The Specifics
Unlike traditional network perimeters, cloud environments multiply rapidly as teams spin up instances, databases, and services without centralized oversight. Blinderman notes that “unmanaged cloud sprawl can increase attack surface and reduce visibility, making it hard, if not impossible, to defend against surprise unknown threats. How can you protect something you don’t know is yours?”
The challenge isn't just technical, it's organizational. Marketing launches a customer survey platform, HR implements a new applicant tracking system, and engineering deploys development environments, all potentially bypassing security reviews. Meanwhile, shadow IT thrives as departments seek agility over approval processes.
When you blend cloud sprawl with the tenacity of cyber bad actors, the problem multiplies. Former FBI Special Agent Darren Mott emphasized that businesses of all sizes are targets. He urges CEOs to prepare for the fact that their companies “are constantly targeted by cyber bad actors from both the criminal and nation-state realms.”
As your attack surface grows and cyber bad actors become increasingly primed to attack, you must race to find and secure your cloud environment. Small and midsize businesses face particular risk because they often lack the resources for comprehensive cloud security governance, yet they're deploying cloud services at enterprise scale.
The financial impact can be catastrophic. A single misconfigured cloud storage bucket can expose millions of customer records, triggering regulatory fines, legal liability, and reputation damage that can take years to recover from.
The Solutions
Implement cloud asset discovery tools that automatically inventory all cloud resources across your organization (we have a dedicated article all about attack surface management).
Establish mandatory security reviews for any new cloud deployments, regardless of size or department.
Create clear policies for cloud resource provisioning and decommissioning.
Conduct quarterly cloud security audits with external experts.
2. AI-Powered Social Engineering
The Threat
What happens when machines perfect human deception? The answer: Nothing good! Artificial intelligence is weaponizing social engineering attacks with unprecedented sophistication, making traditional security awareness training obsolete overnight.
The Specifics
Cybersecurity expert Tamika Bass has watched AI transform the threat landscape in ways that traditional security controls simply cannot address. Modern AI can analyze social media profiles, corporate websites, and public data to craft perfectly targeted phishing campaigns that fool even security-conscious employees.
Bass shares that, “Cybercriminals are using AI to scale, automate, and personalize their attacks, making it difficult to detect and defend against them.” Let’s examine AI-generated deepfake voices and emails. Cybercriminals can impersonate the voices of executives requesting urgent wire transfers, while also sending AI-written emails (seemingly from the executives in question) to pass grammar and style checks that would have flagged previous attempts. This is further supported in the research. In a recent study, a control group of recipients who received arbitrary phishing emails had a click-through rate (i.e., the percentage of recipients who pressed a link in the email) of 12%. In contrast, emails generated by human experts and fully Automated emails both received a 54% click-through rate. In other words, AI is enhancing the capabilities of cybercriminals.
Social engineering is a long-standing threat. Another expert in the cybersecurity space, Jude Fils-Aimé, warns that protecting enterprises from social engineering attacks requires a fundamental rethinking of security culture. He notes, “Threat actors exploit our natural tendencies, often preying on human error, to launch successful attacks.” Traditional annual security training becomes insufficient when attack vectors evolve on a monthly basis.
The psychological manipulation has become surgical. AI systems analyze writing patterns, identify emotional triggers, and craft messages that exploit specific vulnerabilities in organizational communication patterns. They might impersonate a CEO requesting an urgent payment during a board meeting they know is happening based on public calendar information. This is alarming, to say the least!
The Solutions
Implement multi-factor authentication for all financial transactions and sensitive data access.
Establish verification protocols for unusual requests, especially those involving money or data.
Move from annual security training to continuous, scenario-based education programs (using current, up-to-date threats).
Create "trust but verify" cultures where employees feel safe questioning suspicious requests.
3. Authentication Failures
The Threat
Password-based security is failing catastrophically, yet most organizations still rely on authentication methods designed for a simpler, less connected world.
The Specifics
Cybersecurity leader Jameeka Green Aaron, with over 20 years of experience across multiple industries, identifies authentication failures as among the most significant cybersecurity threats we face today. The numbers are stark: The use of stolen credentials (77%) and brute force attacks (21%), usually easily guessable passwords, are the two main points of compromise in data breaches.
The problem extends beyond simple password reuse. Legacy systems often can't support modern authentication methods, creating security islands within organizations. Employees frequently toggle between systems that require different authentication standards, leading to password fatigue and the adoption of dangerous shortcuts.
Business email compromise attacks increasingly target authentication weaknesses rather than trying to break encryption or bypass firewalls. Attackers know that gaining access to one account often unlocks access to many others through single sign-on systems and shared credential patterns.
The remote work revolution has significantly amplified these risks. Employees access corporate resources from home networks with varying security standards, personal devices with inconsistent patch management, and coffee shop WiFi with no security controls. Aaron advises that “we must proactively test our IAM [Identity and Access Management] solutions, determine weaknesses, and then fortify them, all before a bad actor even knows we exist, let alone mount an attack.” We agree, and have devised some ways to do just that!
The Solutions
Mandate multi-factor authentication across all business-critical applications.
Implement passwordless authentication solutions where technically feasible.
Conduct credential exposure monitoring to identify compromised employee accounts.
Establish zero-trust architecture principles that verify every access request (we have a dedicated article all about zero trust).
4. Supply Chain Risk
The Threat
Modern business supply chains are so interconnected that a security failure at one organization can trigger devastating cascade effects across entire industries. In reality, one breach can become everyone's problem.
The Specifics
Cybersecurity expert Lucia Milică Stacy highlights the growing threat of systemic risk as organizations become increasingly dependent on shared infrastructure, vendors, and supply chains. She states, “We are so interconnected to one another that any critical failure in this system could impact multiple organizations within it. Recognizing and mitigating this systemic risk is paramount for Chief Information Security Officers and board directors.” The SolarWinds attack demonstrated how compromising one widely used software vendor could affect thousands of organizations simultaneously.
Third-party risk management has become a critical vulnerability that most organizations handle inadequately. Companies conduct vendor security assessments at the time of contract signing, but rarely monitor their ongoing security posture. Meanwhile, vendors often have access to invaluable data and critical systems that could paralyze operations if compromised.
The interconnected nature of modern business means that a breach at your cloud provider, payment processor, or communication platform can impact your operations even if your direct security measures are excellent. Supply chain attacks systematically target these trust relationships.
Financial services, healthcare, and critical infrastructure face particular exposure because attacks against one organization can undermine public confidence in entire sectors. The costs extend far beyond the initially compromised organization.
The Solutions
Implement continuous third-party security monitoring, rather than relying solely on point-in-time assessments.
Develop incident response plans that account for vendor-originated breaches (we have a dedicated article closely examining incident response plans).
Diversify critical vendor relationships to avoid single points of failure.
Establish clear contractual requirements for vendor security standards and breach notification.
5. The Cybersecurity Skills Crisis
The Threat
The cybersecurity workforce shortage has reached critical levels, creating a dangerous gap between the sophisticated threats organizations face and their ability to defend against them.
The Specifics
The workforce gap in 2024 was 4.8M people, a 19.1% increase from 2023. This isn't just a hiring problem, it's a strategic vulnerability that attackers actively exploit. Organizations with understaffed security teams, inadequate training programs, or over-reliance on a few key personnel face dramatically higher breach risks.
Former DOJ prosecutor and cybersecurity expert Andrew Pak identifies this challenge precisely, "The most significant cybersecurity challenge my clients typically face is a lack of qualified cybersecurity personnel. Sometimes, this results from internal resource constraints, but oftentimes, this results from a lack of qualified personnel in the job market."
The crisis extends beyond pure technical roles. As Andrew notes, "When it comes to services/functions that are cybersecurity adjacent (such as compliance and legal), the problem can be even worse, as it is even more challenging to find talent in these fields that are well-versed in cybersecurity, as they already require significant training in and experience in other subject matters."
The problem compounds through a vicious cycle: security incidents damage organizational confidence in existing security teams, leading to higher turnover and even greater skills shortages. ISC2's 2024 Cybersecurity Workforce Study, which surveyed nearly 16,000 cybersecurity practitioners and decision-makers globally, revealed that over two thirds of respondents (67%) reported some form of shortage of cybersecurity professionals in their organization, while 90% indicated that they face skills shortages at their organizations.
Meanwhile, attackers have professionalized their operations (powered by AI), creating an asymmetric battlefield where sophisticated criminal organizations face understaffed and under-resourced defenders. More than half of those surveyed (58%) believe a shortage of skills puts their organization at significant risk.
Pak offers a comprehensive solution, "We can address that challenge through increased training and education at all levels. The more we can make cybersecurity a core element of any education, the more we can close this gap." Let’s build on his idea.
The Solutions
Make cybersecurity awareness training a priority across all levels of management and staff.
Supplement internal gaps through outside resources with specialized knowledge and experience.
Provide professionals with opportunities to gain competence through informal educational resources and on-the-job training.
Ensure senior management understands cybersecurity risks through tabletop exercises and hands-on training.
The Bottom Line
These five threats share common characteristics that make them particularly dangerous: they exploit trust relationships, evolve rapidly, and cause damage that extends far beyond immediate financial losses. But they're not insurmountable.
The experts featured in our One2 Watch series consistently emphasized that effective cybersecurity isn't about perfect technical solutions, it's about building organizational resilience through people, processes, and technology working in harmony.
Immediate Next Steps
Conduct a rapid assessment of your exposure to each of the five threat areas we covered.
Identify which of the five threats could cause the most business disruption in your specific industry.
Implement some quick wins that can reduce risk immediately.
Develop a longer-term security strategy that addresses the root causes, not just symptoms.
