10 Signs Your Business Has Security Vulnerabilities

You don't need a complicated security report to know if your business is at risk. There are obvious signs.

If you see any of these 10 things, your business is vulnerable. Vulnerable means "will be attacked" — it's only a matter of when.

1. Computers Are Incredibly Slow

Your laptop takes 10 minutes to start. The server freezes when 5 people are using the system. Things that should take 2 seconds take 30.

What It Means

• Malware installed: Viruses, trojans, or crypto miners using your CPU
• Antivirus running poorly: Continuously scanning but never finishing
• Too many background processes: Legitimate apps but misconfigured
• Disk full: 90% capacity used, Windows can't operate normally

What to Do Now:

1. Open "Task Manager" (Ctrl+Shift+Esc on Windows)

2. Look at "Processes" tab — is there anything odd? (Executables with weird names like "svch0st.exe" instead of "svchost.exe"?)

3. Go to "Performance" — is CPU or RAM constantly at 95%+?

If you don't know what's normal, call your IT or a specialist. Slowness is a red flag.

2. You Get "Weird" Emails from People You Know

Your boss emails asking for a money transfer. Your client asks about a package already delivered. Your supplier sends a "new catalog" with a suspicious attachment.

But something feels off.

What It Means

• Your email was hacked: Someone accessed it and is using your account to send malware
• Their email was hacked: We're seeking access through trusted contacts
• Sophisticated impersonation: The name looks good but the email address is slightly different ("juann@gmail.com" vs "juan@company.com")

What to Do Now:

1. DON'T click the link or open the file

2. Call the person on a phone number you already know and ask if they sent the email

3. If they say no, it's an attack. Report it as phishing

4. If you can't reach them, wait

The golden rule: If something feels wrong, it probably is.

3. Former Employees Still Have System Access

Your assistant left the company 4 months ago. Their server credential is still active. Your accountant left a year ago and their VPN still works. Nobody deactivated the accounts.

What It Means

• Unauthorized access guaranteed
• A disgruntled ex-employee could sabotage systems
• Credentials could be sold to criminals
• Risk of data theft or ransomware

What to Do Now:

1. List all employees who left in the last 2 years

2. Verify with IT that their accounts are deactivated

3. Change passwords for any shared access

4. For each system (email, server, VPN, databases), review who has active credentials

This should take 1-2 hours. Do it today.

4. Nobody Uses Multi-Factor Authentication (MFA)

"MFA? No, it's too inconvenient." Everyone uses username and password only. Period.

What It Means

• One compromised credential = full access
• Phishing is enough to get in
• An attacker doesn't need more than two pieces of information

What to Do Now:

1. Enable MFA on email (Microsoft 365, Gmail — takes 20 minutes)

2. Enable MFA on critical systems (VPN, server, databases)

3. Use authentication app (Microsoft Authenticator, Google Authenticator, Authy)

MFA blocks 99.9% of compromised-credential attacks (Microsoft).

5. Passwords Are Shared or Weak

Your team shares the server password. The password is "company123" or "password." Someone has the access password saved on a sticky note on their monitor.

What It Means

• Anyone with physical access can see it
• Everyone uses the same account — no audit trail of who did what
• One shared password means "anyone is an administrator"

What to Do Now:

1. Change all shared passwords to unique ones

2. Use a password manager (Bitwarden free, 1Password, LastPass)

3. Create policy: Minimum 12 characters, numbers, uppercase, symbols

4. Each person has their own account

Cost: $0-$50 USD/year per person.

6. You Have No Backup Policy or Don't Verify It

"We do backup every Friday" — but do you verify it? Test it? Can you restore data?

If you can't answer yes with certainty, it's a problem.

What It Means

• Ransomware leaves you with no data and no way to recover
• Accidental data loss is unrecoverable
• Months or years of work disappears

What to Do Now:

1. Verify your backups run automatically (not manually)

2. Once a month, try to restore a random file from backup — actually do it, don't just assume it works

3. Ensure backups are in a different physical location (not just another disk on the same machine)

4. Encrypt your backups

If you can't restore a test backup within 2 hours, you don't have a backup.

7. Your Software Is Obsolete or Never Updates

Windows 7 running in production. Microsoft Office 2016. Java from 5 years ago. No security patches.

What It Means

• Known vulnerabilities unpatched
• Public exploits that work against your system
• It's like leaving the door open

What to Do Now:

1. Audit what software runs on each machine

2. Update Windows to supported version (Windows 10 or 11)

3. Enable automatic updates

4. For critical software (antivirus, databases), update within 30 days of release

Cost: IT time, possibly new licenses.

8. You Have No Antivirus or It's Outdated

"We don't need antivirus, we trust our employees." Or: you have antivirus from 5 years ago that never updates.

What It Means

• Malware installs without protection
• Your team has no visibility into what's happening on endpoints
• Ransomware can run freely

What to Do Now:

1. Install EDR (Endpoint Detection & Response) — better than traditional antivirus

2. Options: Windows Defender (free, decent), Bitdefender, CrowdStrike, Sophos

3. Enable automatic updates of malware signatures

4. Real-time scanning must be active

Cost: Free to $50 per machine per year.

9. Employees Don't Receive Security Training

"Security isn't my responsibility, it's IT's." Employees click links without thinking. They open files from "clients" without verifying.

What It Means

• Phishing has success rate of 30-50%
• Social engineering works perfectly
• It's the easiest weak point to exploit

What to Do Now:

1. Conduct phishing training (1 hour, minimum annually)

2. Teach them: Links can be fake, files can have malware, "verifying" is their job

3. Create policy: "Suspicious = report, don't click"

4. Use simulation tools (KnowBe4, Gophish) to test and train

Cost: $5-20 per person per year.

10. Nobody Knows What Data You Have or Where It Is

Your company collects customer information. Where do you store it? Who can access it? How long do you keep it?

If you don't know, it's a regulatory and security problem.

What It Means

• Non-compliance with LFPDPPP (Federal Law for Personal Data Protection)
• Fines up to $3.5 million MXN
• You don't know if it was stolen or leaked
• Backups could be compromised without you knowing

What to Do Now:

1. Inventory: Where do you store customer data (local server, cloud, paper)

2. Who has access? (Only those who absolutely need to)

3. How long do you keep it? (Minimum necessary, then delete)

4. Is it encrypted? (In transit and at rest)

5. Document this in a data policy

This is legally required. If you don't have it, you're legally exposed.

How Many of These Signs Does Your Company Have?

• 0-1: You're better than most, but it's not enough
• 2-4: Your risk is moderate to high
• 5-7: Your risk is critical. You're a target
• 8-10: It's surprising you haven't been attacked yet

The Next Step (And It Really Matters)

These aren't theoretical signs. It means your company is exposed.

You don't need a $1 million security team. You need:

1. A diagnosis: What exactly is wrong?

2. A plan: Priorities and costs

3. Implementation: Step by step

At Simiriki, we do exactly that. We audit your environment, identify specific vulnerabilities, and give you an actionable plan.

Remediating identified vulnerabilities costs a fraction of the documented cost of a breach (USD 4.44M global average per IBM Cost of a Data Breach Report 2025). The gap between prevention and post-incident response is measured in orders of magnitude, not percentages.

If you see any of these 10 signs, don't wait for the attack. Contact us for a security audit. It's the most important decision you can make right now.
