Free terminal WiFi at Cape Verde’s airports is convenient but shares the same basic risk profile as any public network anywhere — the connection itself isn’t the danger, what you do on it is.
Quick answer: Avoid logging into banking or other sensitive accounts on airport WiFi without a VPN, and treat mobile data through your eSIM as the safer default for anything you’d rather keep private.

What actually makes public WiFi risky
An open network without a password, common at airport terminals worldwide, makes it technically easier for traffic on the same network to be intercepted — not a certainty, but a real enough possibility that sensitive logins deserve extra caution.
A simple habit: save sensitive tasks for mobile data
Since an active eSIM gives you a private mobile connection the moment you land, saving banking, sensitive email, or anything requiring a password for your cellular connection rather than the terminal WiFi removes most of the risk entirely.
Using a VPN if you do need WiFi for something sensitive
A VPN encrypts your traffic regardless of which network carries it, making it a reasonable safeguard if you specifically need airport WiFi’s speed or your mobile data isn’t yet active — worth installing before you travel rather than trying to set up on unfamiliar WiFi.
Recognizing legitimate networks
Confirm the exact network name with airport signage or staff before connecting — fake networks with similar names occasionally appear in busy public spaces specifically to catch travelers connecting without checking.
Applying this across Cape Verde’s airports
The same precautions apply whether you’re at Sal, Boa Vista, Praia, or São Vicente — none of Cape Verde’s airport networks are inherently less safe than another, so the habits matter more than the specific location, as covered in the individual Sal Airport WiFi guide.
