You’ve probably seen Bitdefender ‘s offers: between the “Individual” and “Family” versions, it’s easy to get lost. On paper, the Family pack is the grail, with 25 protected devices. But who really has 25 computers at home?
The reality is that by purchasing these licenses alone, you’re paying for extra security that you never use.
Comparison: Which Bitdefender is right for you?
| Offer | No. of units | Instant price | Actual cost/month |
| Individual (official website) | 5 | ~49,99 € | 4,16€ |
| Family (official website) | 25 | 79,99€ | 6,66€ |
| Sharesub co-subscriber | 1 | 0€ | 2,39€ |
Why is the individual offer not advantageous if you’re on your own?
The Bitdefender Family offer is incredible because it allows you to create 5 independent Central accounts. It’s the most robust solution on the market. But spending €80 (and up to €124 after one year) all at once to protect a smartphone and a PC is a bad financial calculation.
What is Sharesub?
Before diving into the trick, it’s important to understand the tool. Sharesub is a secure French co-subscription platform.
Imagine a “car-sharing” system applied to your digital services: instead of paying alone for a license for 25 devices that you use only 10% of, Sharesub lets you share the empty spaces with other individuals.
- Secure: The platform acts as a trusted third party for payments.
- Legal: It complies with publishers’ conditions of use, which authorize multi-equipment.
- No commitment: You pay by the month and can stop whenever you want.
Two strategies to reduce your Bitdefender bill
The platform makes it possible to avoid the problem of high initial costs, thanks to two modes of operation.
Become a co-subscriber (lowest price)
It’s the ideal solution if you never want to see another €120 debited from your account, or if you only have 1 or 2 devices (PC, Mac or Smartphone) to protect.
- How it works: You join an existing group on Sharesub and use a vacancy.
- The financial advantage: You pay only your share, i.e. around €2.39/month. It’s a standard monthly subscription, with no cash advance.
- The end of the “Renewal Tax”: Unlike the official site, which commits you for one year before doubling the price, the Sharesub rate is stable. No nasty surprises in 12 months: you stay at the low price for as long as you like.
- Total freedom: There’s no commitment. If you find another solution, or if you no longer need antivirus software, you’re out in one click.
Becoming an owner
This is the recommended strategy if you have more than 5 devices to protect, or if you want to retain total control over your subscription while reducing your costs.
- The principle: You buy your own official license via Bitdefender, then offer the places you don’t use to the community on Sharesub.
- The advantage: By sharing your remaining accesses, your co-subscribers’ contributions directly reduce your initial purchase.
- Result: You benefit from the market’s No. 1 protection on all your devices (up to 25!) for a very low final cost once reimbursements have been received.
The 3 advantages of using Sharesub
1. No more high renewal costs
The greatest danger with antivirus software is forgetting. You subscribe to a special offer, and a year later, Bitdefender charges you the full price (often over €100) without you even noticing. By switching to co-subscriber mode, you regain control: you decide the duration, month by month.
2. Low-cost protection
Joining a group often gives you access to Bitdefender Ultimate Security. This includes :
- VPN Unlimited (normally sold for an additional €34.99/year).
- SecurePass password manager.
- Monitoring the Dark Web for your data.
3. Total confidentiality (multi-account technology)
Unlike other services, sharing Bitdefender via the Family Plan is ultra-secure. You create your own Bitdefender Central account. The group owner can’t see your devices, can’t access your scans, and has no regard for your privacy.
