Start With What You Don’t Know: Why Security Assessments Matter

Data is one of your most important assets, and you can’t protect it if you don’t know exactly where it lives, who can access it, or how it moves through your systems. In security, the unknowns are what hurt you.

That’s the core purpose of a security assessment: to turn unknowns into knowns. When you replace guesswork with evidence, you make smarter decisions, allocate your budget more effectively, and reduce risk in a measurable way.

Below are four types of security assessments that we often use at Arraya to help organizations gain visibility into their environment, understand their risk, and take meaningful action.

1) Business Impact Analysis (BIA): What would it cost if X went down?

Purpose: Identify which systems and data are most critical to your operations and what happens if they’re disrupted.
Key questions it answers:

• Which applications and data are mission-critical?
• How long can we tolerate downtime (RTO) and data loss (RPO)?
• What are the operational, financial, and customer impacts of an outage?

Why it matters: A BIA gives you clarity on what truly matters most to your business, so you can focus resources where they have the greatest impact. It helps prevent overinvesting in low-priority systems while leaving your most valuable assets underprotected.

2) Tabletop Exercise: Will our plan work when it’s not a drill?

Purpose: Rehearse your response to a realistic cyber scenario with the people who will actually handle it.
Key questions it answers:

• Who calls the shots in a crisis?
• Do we know how to escalate, communicate, and make decisions?
• Where do our plans, tools, or roles break down?

Why it matters: An incident is the wrong time to discover that your team isn’t on the same page. Tabletop exercises let you identify and fix process gaps in a safe, low-pressure environment, so when a real incident occurs, you can respond faster and more effectively.

3) Penetration Testing: Where would an attacker get in?

Purpose: Simulate attacker behavior to uncover exploitable weaknesses in networks, apps, or configurations.
Key questions it answers:

• Can an external or internal actor get in?
• What can they access once inside?
• Which vulnerabilities matter most right now?

Why it matters: A penetration test shows you what an attacker could realistically do with the vulnerabilities in your environment. This lets you focus on fixing the most dangerous weaknesses before they can be exploited.

4) Gap Assessment: How do we stack up against best practices?

Purpose: Compare your current controls to a framework (e.g., NIST CSF) or a policy requirement.
Key questions it answers:

• Where are we aligned, partially aligned, or missing controls?
• Which fixes are quick wins vs. longer-term projects?
• How do we show progress to leadership, customers, or auditors?

Why it matters: Gap assessments give you a measurable baseline and a clear roadmap for improvement. They’re especially useful when you need to show stakeholders that you’re investing in security strategically and systematically.

Next Steps: Where Should Your Organization Begin?

The best starting point depends on your current level of visibility and preparedness. You don’t need to take on every type of assessment at once. Instead, focus on the one that will give you the most immediate value.

Use this guide below to determine your best first step:

• If you don’t know what’s most important: Start with a BIA.
• If you have a plan but haven’t tested it: Run a tabletop exercise
• If you want to understand your exposure: Conduct a penetration test.
• If you need a measurable program: Do a gap assessment.

Security isn’t a finish line; it’s a practice. Just like checking every window and door at home, understanding your risks is where business security starts. Whether you begin with a BIA, a tabletop, a pen test, or a gap assessment, the goal is the same: replace uncertainty with clarity, so you can protect what matters most.
