Absolutely not recommended. For a long time now, I’ve been regularly spammed with promotional emails from Link11. Even though I’m not interested, the messages just won’t stop. This aggressive marketing is unacceptable to me and definitely doesn’t come across as professional. Instead of building trust, Link11 does the exact opposite.

Thank you for bringing this experience to our attention. Promotional emails that are perceived as annoying don’t meet our standards, and we’re very sorry about that. We’ve removed your contact details from our marketing mailing list. If you’d like us to make sure that every entry has been deleted, you can reach us anytime at [email protected]. If, contrary to expectations, you continue to receive messages, please let us know right away—we’ll look into it immediately.
Kind regards,
Your Link11 Team

It's hard to believe the outrageous
machinations are being used here!
Without me being a customer of this company or ever having heard of it, 2 of my browsers are simply blocked today.
Suddenly I was forbidden by Link 11 to view an NE online store.
I called them first, assuming that something had gone wrong between us, which is why this store was blocking me. However, the friendly employee assured me otherwise and wanted to keep me as a customer.
Only then did I really see the sender of this page, link11.
The only solution they offered me, in English, was that I had to give them my It address so that they could remove their own block from my browser.
How stupid would you have to be not to realize that this was probably the goal of the whole link11 action in the first place?
Who can help me now to take action against this highly probable cybercrime of the most brazen kind?
Ok. However, please understand that I will not give out my IP address anywhere on command.
Not even if the telephone answer at the time had been more explanatory and binding, as it is here, than your written statement.
( But perhaps you, as a security company for
Internet and cyber-attacks, perhaps it is also possible for you,
solve possible cyber attacks innovatively, even without knowledge of IP addresses?
Comment by Link11 GmbH
Dear Ms. Becker,
Thank you for your feedback. We understand that the situation you have described is irritating and annoying and would like to clarify our position.
Link11 is an IT security company that protects web applications and online stores from cyber attacks - especially DDoS attacks. In this context, an automated protection system is used that can temporarily block requests in the event of suspicious behavior for security reasons. This does not affect you personally, but is based on technical parameters such as IP addresses or unusual traffic behavior. Unfortunately, this can also lead to so-called "false positives" in individual cases - i.e. blocking is carried out in error.
We very much regret that you were temporarily unable to access an online store as a result. However, we would like to emphasize that this is not a "machination" or even "cybercrime", but a purely technical protective measure in the interest of our customers - the operators of the respective website.
If you provide us with your IP address, we can check the case individually and remove any erroneous blocking immediately. We only need this information for technical verification and, of course, in compliance with the applicable data protection laws.
Please be assured that we have no interest in collecting personal data or violating your privacy. Our aim is to keep websites secure and accessible - also for you as a user.
Yours sincerely
Your Link11 team

Unfortunately, very poor communication. They make you guess what your costs will be, and only after sending multiple emails do you receive a rather vague response. As soon as you fall within their "guidelines," which they don’t tell you about, you are simply ignored.

We were involved in a health day at Link11 in Frankfurt and the collaboration was very pleasant and professional. The team is very motivated and the company is innovative. Health, well-being and the working atmosphere are very important and promoted here. We'd be happy to do it again 🙌🏼
