Small and mid-sized businesses are facing the same cybersecurity threats as enterprise organizations — but with a fraction of the resources. That’s why it’s critical to take full advantage of high-value free IT security tools in 2025.
These tools help you strengthen your security posture, uncover hidden risks, and optimize performance — without the upfront investment.
Here are 10 free resources every SMB should be using right now, including one that’s purpose-built for Ohio businesses: Securafy’s Free 47-Point Network Assessment.
🔗 www.securafy.com/free-network-assessment
Before you can secure your systems, you need visibility. That’s where Securafy’s 47-point network assessment comes in.
This free, confidential evaluation is designed for small and mid-sized businesses that want clarity on their IT health, risk exposure, and compliance readiness — without paying for a full security audit.
Security Risk Detection: Pinpoints vulnerabilities in firewalls, endpoints, and remote access systems. Uncovers signs of potential breaches, viruses, or rogue insiders.
Network Performance Analysis: Identifies slow systems, bottlenecks, and underperforming hardware that may be affecting operations or uptime.
Compliance Readiness Review: Checks your alignment with HIPAA, PCI DSS, and other applicable regulations — with specific insights for healthcare, legal, and financial services.
Cost-Saving Opportunities: Highlights IT inefficiencies and overspending areas, giving you actionable ways to reduce monthly support and infrastructure costs.
Most small businesses rely on external IT vendors but lack visibility into whether systems are actually protected. This assessment is local, no-pressure, and built for SMB decision makers who need real answers — fast.

Wireshark is the industry standard for network protocol analysis — and it’s completely free. It allows your IT team or service provider to capture and inspect traffic at a granular level.
Monitors all incoming and outgoing network activity
Identifies suspicious data flows or abnormal traffic patterns
Helps pinpoint misconfigured systems, bandwidth issues, or malware-infected devices
If you’re experiencing slow performance, potential intrusions, or strange network behavior, Wireshark helps you investigate in real time. It’s an essential tool for diagnosing threats or bottlenecks before they cause business disruption.
Best for: IT teams, managed service providers, or technical leaders responsible for network stability.
OpenVAS is a powerful open-source vulnerability scanning platform that gives you enterprise-grade security scanning at zero cost.
Scans your internal and external systems for thousands of known vulnerabilities
Delivers risk scores and remediation advice
Continuously updated with new CVEs (Common Vulnerabilities and Exposures)
Most attacks exploit known, unpatched vulnerabilities — and many SMBs aren’t running regular scans. OpenVAS helps you find and fix exposures before attackers do.
Best for: Ohio businesses with in-house IT or outsourced MSPs that want more control over vulnerability management.
KeePassXC is a free, open-source password manager that helps your organization enforce strong credential hygiene — one of the top defenses against phishing and data breaches.
Stores and encrypts passwords locally — no cloud dependency
Enables employees to generate and store complex, unique passwords
Organizes credentials by department, function, or role
Passwords are still one of the easiest ways attackers gain access to systems. For Ohio law firms, medical practices, or accounting teams with access to sensitive data, a password manager is a minimum requirement.
Bonus: KeePassXC can be deployed in air-gapped or highly regulated environments where cloud tools aren’t allowed.
🔗 cisa.gov/free-cybersecurity-services-and-tools
The Cybersecurity and Infrastructure Security Agency offers a suite of free services for critical infrastructure and SMBs, including:
Vulnerability scanning of public-facing systems
Email security reviews (DMARC, SPF, DKIM)
Remote phishing assessments
Cyber hygiene reports and penetration testing (for eligible organizations)
CISA’s tools give you access to government-grade threat intelligence and proactive scans — at no cost. This is especially relevant for Ohio businesses involved in public contracts, healthcare, utilities, or logistics.
Use CISA’s free scans alongside Securafy’s network assessment for complete internal/external visibility.
NetSpot helps you perform a wireless site survey to optimize your Wi-Fi coverage and performance.
Maps signal strength across physical locations
Identifies dead zones and overlapping frequencies
Helps plan access point placement for better connectivity
For offices, clinics, or retail spaces that rely on wireless systems, poor signal strength impacts productivity and security. Weak Wi-Fi zones are also prime entry points for unauthorized access.
NetSpot helps you harden physical-layer security by ensuring stable, reliable wireless coverage.
🔗 fing.com
Fing is a free network scanning tool that provides visibility into every device connected to your network.
Discovers all active devices — even rogue or shadow IT assets
Identifies open ports, system names, and vendor info
Sends alerts when new devices connect
Unsecured or unknown devices are one of the biggest blind spots in SMB security. Fing helps small businesses monitor environments in real time and detect unauthorized access before it becomes a threat.
Pair it with your network assessment findings to maintain visibility between audits.
Zabbix is a free, enterprise-grade monitoring platform for networks, servers, and cloud infrastructure.
Tracks system performance metrics, uptime, and health status
Sends real-time alerts based on thresholds or anomalies
Supports custom dashboards and integrations
Zabbix helps SMBs implement proactive IT management. It’s especially useful for distributed workforces or growing teams where visibility across endpoints is essential.
Use it to monitor key assets highlighted in your Securafy network report.
Snort is a well-established open-source intrusion detection and prevention system (IDS/IPS).
Monitors network traffic for malicious activity
Detects port scans, brute-force attempts, malware behavior
Can block or log suspicious traffic based on rules
Most SMBs don’t have real-time threat detection in place. Snort fills that gap — especially for companies managing their own firewall or edge devices.
Integrate it with your perimeter security findings from your Securafy network assessment for layered protection.
This free training program helps business owners and employees implement basic cyber hygiene practices.
Training modules on phishing, MFA, password policy, and remote work security
Templates for internal cybersecurity policies
Self-paced lessons for technical and non-technical staff
Many breaches begin with human error. This program gives SMBs a structured, low-cost way to improve internal awareness and reduce avoidable risk.
Combine it with your Securafy network report to guide follow-up training and awareness campaigns.
You don’t need a six-figure security budget to make meaningful improvements. These free tools — when used strategically — can help your business:
Detect vulnerabilities
Improve system performance
Train employees
Justify future investments
