# SDCSecurity vs Portal.io

The clearest difference is rating: SDCSecurity at 5.0 against Portal.io's 3.8. Portal.io's advantage is ads (none vs shown) and update cadence (every 2 months vs every 20 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SDCSecurity holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Portal.io has 30 ratings behind it against 6, so its average is the more settled of the two.

SDCSecurity ships an update every 20 months, Portal.io every 2 months. The most recent releases landed on October 6, 2026 and October 14, 2026 respectively.
