What Is CISA? 4 Cybersecurity Organizations Every Business Should Know

Small business network protected by cybersecurity systems

October is Cybersecurity Awareness Month, a good time for businesses to review an increasingly important question:

How prepared is your company for a cybersecurity incident?

Cybersecurity is no longer just an IT responsibility. Business owners and managers also need to understand where to find reliable guidance, how to structure their security strategy, and who to contact when a cyber incident becomes a crime.

In the United States, several organizations play important roles in cybersecurity. For small and midsize businesses, four names are particularly useful to understand:

→ CISA→ NIST→ FBI→ FTC.

Each serves a different purpose.

1. CISA: Cybersecurity Alerts, Guidance, and Prevention

CISA stands for Cybersecurity and Infrastructure Security Agency.

Part of the U.S. Department of Homeland Security, CISA helps strengthen the security and resilience of the nation’s cyber and physical infrastructure.

For businesses, CISA is valuable because it provides practical resources related to:

  • Current cybersecurity threats
  • Critical vulnerabilities
  • Ransomware
  • Phishing
  • Account security
  • Software vulnerabilities
  • Incident response
  • Cybersecurity best practices

CISA also publishes alerts when important security vulnerabilities are actively being exploited.

In simple terms:

CISA helps businesses understand what threats exist and what they can do to reduce their exposure.

For companies without a dedicated cybersecurity department, CISA can be an important source of reliable and actionable information.

2. NIST: A Framework for Building a Cybersecurity Strategy

Many businesses have antivirus software, backups, firewalls, and other security tools.

But having security products does not necessarily mean the company has a cybersecurity strategy.

That is where NIST – the National Institute of Standards and Technology – becomes important.

NIST developed the Cybersecurity Framework 2.0, which helps organizations manage cybersecurity risk through six key functions:

Govern → Identify → Protect → Detect → Respond → Recover

These functions encourage businesses to think beyond individual security products.

For example:

  • Govern: Who is responsible for cybersecurity decisions and risk?
  • Identify: What devices, applications, users, and data does the company have?
  • Protect: What controls are in place to protect those assets?
  • Detect: Can the organization identify suspicious activity?
  • Respond: What happens when an incident occurs?
  • Recover: How quickly can the business restore operations?

NIST also provides guidance specifically designed for small and midsize businesses that may not have mature cybersecurity programs.

In simple terms:

NIST provides a roadmap for organizing cybersecurity as a business risk.

3. FBI: When a Cyber Incident Becomes a Crime

Not every cybersecurity incident remains a technical problem. Some become criminal matters, including:

The Federal Bureau of Investigation – FBI operates the Internet Crime Complaint Center, or IC3, where businesses and individuals can report suspected Internet-related crimes. According to the FBI’s 2025 Internet Crime Report, reported losses related to Internet crime exceeded $20 billion.

For businesses, timing can be critical. If an employee sends money to a fraudulent account or attackers compromise a business email account, knowing where to report the incident can help the organization respond faster.

In simple terms:

When cybersecurity becomes cybercrime, the FBI is one of the organizations a business should know.

4. FTC: Protecting Data Is Also a Business Responsibility

The Federal Trade Commission – FTC approaches cybersecurity from another perspective. Its role includes consumer protection and business practices involving privacy and information security.

The FTC provides cybersecurity resources for small businesses on topics such as:

  • Network security
  • Software updates
  • Backups
  • Phishing
  • Ransomware
  • Vendor security
  • Remote access
  • Protecting sensitive information

This distinction is important because cybersecurity is not only about stopping hackers. Businesses are also responsible for understanding what information they collect, who can access it, how it is protected, and what happens if that information is exposed.

In simple terms:

The FTC reinforces that protecting information is not only an IT issue — it is a business responsibility.

Four Organizations, Four Different Roles

OrganizationMain Role for Businesses
CISAThreat alerts, vulnerabilities, prevention, and guidance
NISTCybersecurity frameworks and risk management
FBI / IC3Cybercrime reporting and investigation
FTCData security and consumer protection

These are not the only organizations involved in cybersecurity in the United States, but understanding these four gives business leaders a strong starting point.

The Bigger Question: Is Your Business Actually Prepared?

Knowing these organizations is useful, but reading cybersecurity recommendations does not automatically make a business secure. The more important question is whether those recommendations are actually being implemented.

Ask yourself:

  • Is Multi-Factor Authentication enabled on critical accounts?
  • Are computers and network devices regularly updated?
  • Do you know which devices are connected to your network?
  • Are backups tested, or do you simply assume they work?
  • Is suspicious activity being monitored?
  • Do employees know how to recognize phishing attempts?
  • Does the company know what to do if an account is compromised?
  • Is there an incident response plan?

And there is another question many small businesses overlook:

Was your network designed to protect your business — or simply to provide Internet access?

Many companies continue to operate using only the router installed by their Internet service provider. As long as the Wi-Fi works and employees can access the Internet, everything may appear normal. However, connectivity and cybersecurity are not the same thing. A network can function perfectly while still lacking the security controls needed to protect the business. If you are not sure who should manage this in your company, our guide on in-house IT vs. Managed IT vs. reactive IT can help.

Five Things to Review This Cybersecurity Awareness Month

October is a good opportunity to review a few fundamentals.

What to ReviewWhat to Do
1. Multi-Factor AuthenticationEnable MFA for email, financial systems, administrative accounts, and cloud applications.
2. Security UpdatesKeep computers, applications, firewalls, and network devices properly updated.
3. BackupsVerify that backups exist and test that your data can actually be restored.
4. Network SecurityReview firewall settings, Wi-Fi configuration, connected devices, and network access.
5. Incident ResponseDefine who to contact and what steps to follow before a security incident occurs.

FREQUENTLY ASKED QUESTIONS

What does CISA stand for?

CISA stands for the Cybersecurity and Infrastructure Security Agency, part of the U.S. Department of Homeland Security. It shares alerts, guidance, and free resources to help organizations reduce cyber risk.

Where should a business report a cyberattack or online fraud?

Businesses can report cyber-enabled crimes to the FBI at ic3.gov. If money was sent to a fraudulent account, contact your bank immediately, since acting quickly can help freeze the funds.

Is the NIST Cybersecurity Framework useful for small businesses?

Yes. The NIST Cybersecurity Framework 2.0 is free and voluntary, and NIST publishes quick-start guides designed specifically for small businesses without a formal security plan.

Why should Texas businesses pay attention to cybersecurity?

According to the FBI’s 2025 Internet Crime Report, Texas ranked second in the nation for cybercrime losses, with more than $1.8 billion reported. Small businesses are frequent targets of email fraud and ransomware.

Cybersecurity Starts Before the Attack

“There are only two types of companies: those that have been hacked, and those that will be.”
— Robert Mueller, former FBI Director

CISA, NIST, the FBI, and the FTC each play a different role, but together they point to the same lesson: cybersecurity depends on preparation. Identifying your systems, testing backups, and deciding how to respond should not begin after an attack is discovered.

Cybersecurity Awareness Month is a good moment to stop treating security as a product you buy and start managing it as what it has become: an operational and business risk.
