EnglishPhoneCrypt Professional vs Universal vs Voice vs Starter: What's the Difference?
Updated
SecurStar's PhoneCrypt line splits into four products, and the main dividing lines are how many sides need the software, what gets encrypted, and price. PhoneCrypt Professional (499.00 €) is the full package: voice, chat, and data encryption for iPhone/Android, Windows, and PBX systems. PhoneCrypt Universal covers calls even when only one side uses encryption, with a 4096-bit scheme and an anonymous phone number. PhoneCrypt Voice and PhoneCrypt Starter are the remaining options, with Starter currently offered for free. The site's product listing gives headline features and prices but does not publish a full side-by-side feature matrix, so anything beyond what's listed below should be confirmed with SecurStar directly.
The four products at a glance
| Product | What the site says it does | Price signal |
|---|---|---|
| PhoneCrypt Professional | Military-strength telephone encryption; encrypts voice, chat, and data communication (pictures etc.); secures iPhone/Android, Windows, and PBX systems | 499.00 € |
| PhoneCrypt Universal | Secures telephone calls even if ONLY ONE SIDE uses encryption (4096 Bit); anonymous and untraceable telephone number; usable worldwide without roaming | Not listed on the page |
| PhoneCrypt Voice | Listed as a product category under Phone encryption | Not listed on the page |
| PhoneCrypt Starter | Listed as a product category; announced as "NEW & FREE," for Win XP / Win 7 / Win 8 / Win 10 / Win 11 | Free |
The real decision: one-sided or two-sided encryption
The most consequential difference is in the descriptions themselves.
PhoneCrypt Universal is the only product whose description explicitly addresses the one-sided case: it "secures telephone calls even if ONLY ONE SIDE uses encryption." That matters when you can't control what the person on the other end has installed. It also advertises an anonymous, untraceable number and worldwide use without roaming.
PhoneCrypt Professional is described as encrypting voice, chat, and data, and as securing mobile phones, Windows, and PBX systems. Its description does not state that it works when only one side is encrypted, so if one-sided operation is your requirement, Universal is the product the site actually claims it for.
What each product is built for
PhoneCrypt Professional — broadest coverage
Choose this if you need more than calls: the listing covers voice, chat, and data (pictures and similar), across iPhone/Android, Windows, and PBX. It's the most expensive item in the line at 499.00 €, which fits a multi-channel, multi-platform deployment rather than a single phone.
PhoneCrypt Universal — calls to non-users
Choose this if the person you're calling won't or can't install anything, or if you need an anonymous number and worldwide use without roaming. The 4096-bit figure is the one the site attaches to this product.
PhoneCrypt Voice — voice-only option
The site lists PhoneCrypt Voice under Phone encryption but gives no feature description or price on the page. If your need is strictly voice and nothing else, this is the name to ask SecurStar about, since the page doesn't let you compare it on features.
PhoneCrypt Starter — free entry point
Starter is the only product flagged as free, and the only one with stated OS support: Win XP / Win 7 / Win 8 / Win 10 / Win 11. That Windows-only framing suggests it is not the mobile product. Treat it as a low-commitment way to try the technology rather than a replacement for Professional or Universal.
How to decide
- Do both sides need to run PhoneCrypt? If no, start with Universal — it's the only one the site claims works one-sided.
- Do you need chat and data, not just voice? Professional is the only listing that names voice, chat, and data together.
- Do you need mobile (iPhone/Android) or PBX coverage? Professional names these explicitly; Starter names only Windows versions.
- Is cost the constraint? Starter is free; Professional is 499.00 €. Universal and Voice have no price on the page, so request a quote before assuming they sit between those two points.
- Do you need an anonymous number or roaming-free worldwide use? Universal is the only product described with those attributes.
What the page doesn't tell you
- No prices for PhoneCrypt Universal or PhoneCrypt Voice.
- No feature description for PhoneCrypt Voice beyond its category name.
- No compatibility list for Universal, Voice, or Professional (Starter is the only one with stated OS versions).
- No statement about whether Professional also works one-sided, or whether Universal also handles chat and data.
Because of those gaps, confirm the specifics with SecurStar before buying — particularly the one-sided question and platform support, since those are the two points where the products most clearly diverge.
