What is MFA and Why Your Business Needs It Now
September 19, 2025For many small to medium-sized business owners, the world of cybersecurity can feel like a foreign language. You hear terms like VPN, Firewall, and Endpoint Protection thrown around, but it’s hard to grasp what they actually do and, more importantly, how they work together to protect your business.
At Krypto IT, we believe you don’t need to be an expert to understand your security. You just need a simple, clear way to see how it all fits together. Think of your company’s network and data as a high-security office building. Each security tool is a different layer of defense, working in concert to keep everything inside safe.
The Firewall: Your Building’s Security Guard and Main Gate
Imagine your office building has a highly trained security guard stationed at the main gate. This guard’s job is to inspect everyone and everything that tries to enter or leave the building.
This is exactly what your firewall does for your business network. A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a set of security rules. It’s the first line of defense, preventing unauthorized access and malicious data from reaching your network. Just as a security guard checks IDs and logs visitors, a firewall checks data packets and blocks anything that looks suspicious or doesn’t have permission to pass.
The VPN: Your Private, Secret Entrance
Now, what if you have a sensitive document that needs to be delivered from a different location to your office building? You wouldn’t just send it through the public mail; you’d hire an armored car to take a private, secure route to a secret back entrance.
This is the job of a Virtual Private Network (VPN). A VPN creates an encrypted tunnel over a public internet connection, allowing you and your employees to securely access your company’s network and data from a remote location, like a coffee shop or a home office. Without a VPN, that data travels over the public internet, where it can be intercepted by anyone. A VPN ensures that your data is safe and private, as if you were in the office itself.
Endpoint Protection: The Office Room Doors and Locks
Once inside the building, you still have different offices, server rooms, and filing cabinets. Not everyone should have access to every room. Each room has a lock on its door and a dedicated security system.
This is where Endpoint Protection comes in. An “endpoint” is any device that connects to your network, such as a laptop, desktop, server, or smartphone. Endpoint protection is a suite of security tools installed directly on each of these devices. It’s like putting a lock on every single door and a security camera in every room.
Endpoint protection software protects against a variety of threats that might bypass your main firewall, including:
- Malware and Viruses: It detects, blocks, and removes malicious software.
- Ransomware: It prevents cybercriminals from encrypting your data and holding it hostage.
- Spyware: It stops malicious software from secretly monitoring your activities.
Even if a malicious file gets past your firewall (for example, through an email an employee opens), endpoint protection is the last line of defense on the device itself, protecting your data and your network from the inside.
The Complete Security Stack: Working Together
So, how do all these pieces work together?
- The Firewall (your security guard) inspects traffic at the main gate, blocking the vast majority of threats from even entering your network.
- The VPN (your private entrance) ensures that your employees can safely access your network from anywhere without exposing sensitive information.
- Endpoint Protection (the locks on your doors) secures every individual device and data point, providing a last line of defense against any threat that manages to get through the outer layers.
Just as a security guard and a locked door are useless without each other, a comprehensive IT security strategy requires a holistic approach. Relying on just one or two of these tools leaves your business vulnerable. A hacker who is stopped by your firewall today might find a way around it tomorrow, but a layered defense ensures they will be stopped again by your endpoint protection.
