IT Glossary
What is a VPN?
Virtual Private Network: an encrypted tunnel linking a device to a network or to the internet — with two distinct meanings: corporate and consumer.
Two quite different products share the three letters VPN, and untangling them saves companies from buying the wrong one. The corporate VPN — the original meaning — is the encrypted tunnel through which an employee at home or on the road reaches internal resources: the file server, the ERP, applications that should never be exposed to the open internet. The laptop virtually joins the company network, with strong authentication at the door; two-factor login is non-negotiable here, because a VPN account guarded by a lone password is the classic entrance through which ransomware walks in looking legitimate. Access should be granted on a least-privilege basis and revoked the day someone leaves; modern zero-trust solutions refine the same need by granting access per application, with continuous identity checks, instead of opening the whole network. The consumer VPN — the one in advertisements — tunnels your traffic to the provider's servers before it exits to the internet; its honest uses are protection on untrusted hotel and airport Wi-Fi and changing your apparent location, for instance to test how your site looks from another market. What it does not do, despite the marketing: it does not make you anonymous (you have moved trust, not removed it), does not stop phishing or malware, and substitutes for no other security measure. Company takeaway: internal access deserves a properly configured corporate VPN or zero-trust setup; traveling laptops may add a decent commercial VPN as an extra layer; and "total security in one click" deserves a polite smile.

Why it matters for your business
Internal resources reachable without exposure
The ERP and company servers stay closed to the internet — employees enter through an encrypted tunnel with 2FA, attackers stay at the door.
Hybrid work on serious infrastructure
From home, on the road, at a client — the same access as at the office, encrypted and logged; flexibility without the security compromise.
Protection on other people's networks
On hotel or airport Wi-Fi, the encrypted tunnel makes local interception useless — travel hygiene for laptops carrying company data.
Frequently asked questions
Employees access company systems from home — what is the correct setup?
The minimum standard: a corporate VPN with mandatory 2FA (a password alone at the network gate is unacceptable), role-based granular access rather than the whole network for everyone, managed devices (an unmaintained personal laptop is a risk imported into the network) and a living access register with revocation on the day of departure. For internal web applications, ask your IT provider about zero-trust access as the modern alternative.
Is a commercial VPN subscription worth it for a company, or is it marketing?
On its real merits: for laptops that often work from hotels, airports and public spaces — yes, as a cheap extra layer, and for occasional geolocation needs such as checking your online presence from other markets. As a company security solution — no: it touches none of the vectors that actually matter, so 2FA everywhere, tested backups, endpoint protection and training come first in any budget.
Will a VPN slow down our connection?
Slightly, and usually imperceptibly with serious providers: encryption adds a small processing cost and routing through the VPN server adds latency that grows with distance. Modern protocols like WireGuard cut the overhead dramatically; pick nearby exit points, and for office VPNs size the internet line for the number of simultaneous tunnels — a "slow VPN" is more often an undersized office connection.
