Cyber Hygiene for Business: Risk Calculation and ROI

Basic Cybersecurity Hygiene for Mid-Sized Business: Tools and ROI Calculation

In mid-sized companies (50–500 employees), information security budgets often do not exceed the salary of a single junior developer. However, a single data breach or ransomware incident can lead to losses in the tens of millions of dollars. Consider this case: a sales manager at a 200-person manufacturing firm copied the client database, deal history, and pricing policy onto a USB drive. The lack of role-based access control, automated account blocking upon termination, and Data Loss Prevention (DLP) led to the churn of key clients generating 80% of revenue. Such risks are mitigated with basic measures within weeks for hundreds of thousands of dollars.

Mid-sized businesses are vulnerable: there is lots of data, but little protection. Expected annual losses from incidents exceed the cost of hygiene. ROI is positive, and payback occurs within months.

Risk Calculator: Converting Threats to Dollars

For assessment, use a model accounting for revenue, company size, downtime costs, recovery expenses, compliance fines (GDPR/CCPA), and reputational damage. Results include:

• Expected annual losses with baseline incident probability.
• Cost of cybersecurity hygiene.
• ROI and payback period.

In detailed mode, breakdown by items: downtime (days without work), IT recovery, legal fees, notifications, fines, client churn. For companies with 200–300 employees and revenue in the billions, basic hygiene costs less than $1M/year, while an incident can cost tens of millions.

What's Included in Security Hygiene: 10 Key Categories

Security hygiene is a basic set of measures eliminating 70–80% of typical threats without requiring a full SOC or SIEM. The focus is on automation and processes.

Workstation Protection

• Antivirus/EDR with updated databases and behavioral analysis.
• Centralized policy management.
• Principle of Least Privilege (PoLP).

Ransomware and trojans are detected at early stages.

Email Protection and Anti-Phishing

• Filtering on servers and clients.
• Regular phishing simulations.
• Training on real cases (74% of incidents are due to human factor).

Network Perimeter

• NGFW with traffic inspection, IPS/IDS.
• Website and protocol filtering.

Access Management (MFA, IAM, PAM)

• MFA on email, VPN, RDP, and portals.
• Role-based model in AD/LDAP.
• Automated account blocking upon termination (AD and HRIS integration).
• Quarterly review of privileged accounts.

Backups

3-2-1 Rule: three copies, two media types, one offline.

• Regular recovery tests.
• Define RTO/RPO.
• Ransomware scenario planning.

Log Collection and Monitoring

• Centralized log stack.
• Basic correlations and alerts.
• Assigned responsible parties.

Vulnerability Management

• Quarterly scanning.
• Prioritization of critical patches.

DLP and Leak Control

• USB storage restriction.
• Audit of critical file transfers.
• Rules for accidental and intentional leaks.

Role Model and Offboarding Processes

• Set of roles instead of "access for all".
• Checklist: access, tokens, external services.
• Automation.

Training

• Short sessions and simulations.
• Review of internal cases.

Cost and ROI: Numbers Without Illusions

For 200–300 employees: $200k–$500k/year for licenses and support. One incident: $1M–$10M+ (direct + indirect). Prevention is cheaper even for 50–100 employees if reputation is considered.

| Component | Cost/Year, USD | Risk Covered |

|-----------|---------------------|------------------|

| EDR + MFA | $50k–$100k | 40% of incidents |

| NGFW + DLP | $100k–$200k | Leaks, Perimeter|

| Backups + Training | $50k | Ransomware, Phishing |

Implementation Plan: From Scratch in 1–3 Months

• Enable MFA everywhere (1–2 days).
• Test backups (1 week).
• Launch phishing simulation (1 week).
• Implement role model and offboarding processes (1–2 months).

Transition to SOC: when alerts are overloaded, working with Critical Information Infrastructure, or due to regulatory requirements.

What's Important

• Security hygiene eliminates 70–80% of typical threats cheaper than one incident.
• Automated blocking upon termination prevents database leaks.
• ROI is positive for companies from 200 employees, payback — months.
• Start with MFA, backups, and role model.
• Without processes, technology works at half capacity.
