Threat

What is a threat?

In cybersecurity, a threat is anything that could exploit a vulnerability to cause harm. That includes the attacker (the threat actor), the method they use (the threat vector), and the broader conditions that make an attack possible.

The distinction between threat, vulnerability, and risk is fundamental:

• Vulnerability is a weakness in your system.
• Threat is something that could exploit that weakness.
• Risk is the combination of the two: the probability that a threat will exploit a vulnerability and the impact if it does.

You can't eliminate threats (you can't stop attackers from existing), but you can reduce vulnerabilities (patching, configuration hardening) and manage risk (prioritization, controls, insurance).

Types of threat actors

Not all threats come from the same place or carry the same motives:

• Cybercriminal groups. Financially motivated. They deploy ransomware, steal data for sale, conduct business email compromise, and run credential-harvesting campaigns. Most attacks against startups come from this category.
• Nation-state actors. Government-sponsored groups focused on espionage, intellectual property theft, or sabotage. Typically target defense, critical infrastructure, and technology companies, though startups in sensitive sectors can be targets.
• Insider threats. Employees, contractors, or partners with legitimate access who misuse it, either maliciously (theft, sabotage) or negligently (accidental data exposure, misconfigurations).
• Hacktivists. Ideologically motivated actors who deface websites, leak data, or disrupt operations to make a political or social statement.
• Opportunistic attackers. Less sophisticated actors who scan the internet for low-hanging fruit: known vulnerabilities, default credentials, exposed services. Automated and indiscriminate, making every internet-facing system a potential target.

Why threats matter for startups

1. Threat awareness drives smart prioritization. Understanding which threats are most relevant to your business helps you prioritize security investments. A fintech startup handling payment data faces different threats than a developer tools company. Your threat model should reflect your specific industry, data, and technology stack.
2. Threat intelligence makes CVSS actionable. A CVSS score tells you how bad a vulnerability is in a vacuum. Threat intelligence tells you whether anyone is actually targeting it. Combining CVSS with threat context (EPSS scores, KEV status, active campaign intelligence) turns static severity into dynamic risk prioritization.
3. Threats evolve faster than defenses. AI-powered phishing, ransomware-as-a-service, and supply chain attacks are all expanding the threat landscape. Static security postures become outdated quickly. Continuous monitoring and vulnerability management are necessary to keep up with evolving threats.
4. Compliance requires threat awareness. SOC 2 and ISO 27001 both expect you to maintain a risk assessment that identifies relevant threats. Auditors want to see that you've thought about who might attack you, how, and what you've done about it.
