I just cant seem to figure it out how to get it to work...? even though Im on server2012 R2 fully updated, with SQL 2012 SP4. No matter what i do the Sophos Installer always says:
(x) SQL Server instance does not support TLS 1.2
(x) There is no certificate installed that can be used with SQL Server
I ignored these warnings and Installed SEC5.5.1 anyway as it still works with TLS1.0, but i relly want it to work with TLS1.2, Anybody else have any similar issues?
I am in the process of updating from 5.4.1 and have outcome all but the stated instance support error. I too am on 2012 SP4 /w CU 10. I've tried many different things after ensuring it was not anything to do with an encrypted connection to the SQL server.So I decided to log a ticket with Sophos to get their explanation on the issue. I'm wondering if it is simply checking for a version number that is different, below mine is stated as 11.4.7001.0 which might identify express version over other versions.
In your case the cert issue is that you will need to configure a certificate for use with the SQL Server. We have an enterprise CA so it's quite straightforward for me (just remember to configure all the alternate names you might be using).

Can let you know what they reply.Cheers,Grant
In reply to Grant Joslin:
Thanks for this.
Did you get a helpful Reply?
Would be grateful if you can share it with us.
In reply to Redfern:
Do a quick research this is a common issue. The installer is unaware which version of SQL is really compatible with TLS 1.2
Hi Shahid,I got a reply that said they are discussing it with their product team and will get back to me. I'm sure the post below is spot on with simple installer issues, but I need an official response from Sophos for our compliance. Will update the thread when they provide such information.best wishes,Grant
Thanks Grant. That is one topic that's of importance to us.
In reply to Big_Buck:
yep no worries, if I'm a slow getting back to this thread it's only because it's a slow process with the Sophos support team. So far they have just referred me to these two links below, which are the same as those referenced during this installer.-----------------------------------------Article ID: 127521Title: Enterprise Console - Database connection checkURL: https://sophos.com/kb/127521-----------------------------------------The KBA also links to a Microsoft page that describes what needs to be done in order to prepare the SQL server for TLS 1.2:https://support.microsoft.com/en-us/help/3135244/tls-1-2-support-for-microsoft-sql-server
Slightly annoying as the initial ticket a logged included output from the dbcheckconnection.exe tool.regards,Grant
Exactely the same here. They referred us to the link already provided in the installation instructions. dbconnection.exe, logs, et.c.
Sophos got back to me today. and..yep..you guessed it, they RE-referred me to the article!
And they are avoiding speaking to me over the phone about this. One of the engineers that i spoke to told me straight of the bat that he doesn't no much about SQL etc..like okay, but then why are you picking up a ticket that involves SQL?
They said they'll look into it further and let me know.
Hi guys,I'm going to take a different approach at this point. I found the xls matrix really quick and it appears SQL 2016 SP1 is the latest version supported with 5.4.1. So I'm going to upgrade SQL to this version as it should have the added benefit of exposing the "trace" debug in SQL extended events which will show me the SSL handshake (and what version it is, e.g. TLS 1.2).
So working with the article below I should already see this information using SQL 2012 SP4, but I can confirm on a few different SQL boxes that I never see this option. But I do see it on an SQL 2016 SP1 box.
The SQL instance is on the same box and is just SQL express, so I'll just snapshot the VM before upgrading, and can rollback if any problems are found.I'll report back in once I've completed and check the above work.Ta,Grant
Can’t wait to see the result of this ...
Okay, so I have got to the root of the issue for my environment. I am running SEC 5.4.0 with SQL Express 20012 SP4. I get the following output from the installer:
(/) Operating system is ready to use TLS 1.2
(/) Installed .NET Framework supports TLS 1.2
Connection to the SQL Server established
(/) SQL Server TCP/IP protocol is enabled
(/) There is a certificate installed that can be used with SQL Server
(/) SQL Server Native Client library supports TLS 1.2
Everything looks supported and I should follow the KB’s: ----------------------------------------- Article ID: 127521 Title: Enterprise Console - Database connection check URL: https://sophos.com/kb/127521 ----------------------------------------- The KBA also links to a Microsoft page that describes what needs to be done in order to prepare the SQL server for TLS 1.2: https://support.microsoft.com/en-us/help/3135244/tls-1-2-support-for-microsoft-sql-server
However, no joy for me at this point. I try to follow this article to see what version of TLS is really being used:
Still no joy as there is no extended event for “trace” even though the article says SQL 2012 SP4 is supported.
At this point I look to upgrade to SQL 2016 SP1 and realise that a minimum SEC version of 5.4.1 needs to be installed.
I first verified a successful upgrade to SEC 5.4.1, and then went ahead and upgraded to SQL 2016 SP1. At this point I can see errors with the SEC connection to the DB and SEC wont open.
So I enabled TLS 1.1 and TLS 1.0 via the registry, rebooted and now SEC is working. I can also trace the DB connections and see that SEC 5.4.1 is using TLS 1.0
I can also verify that the SQL mgt studio is using TLS 1.2
Now when I run the installer DBcheckconnection I can a much better outcome.
(/) Operating system is ready to use TLS 1.2
(!) SQL Server instance can be configured to use TLS 1.2
Encrypted connection to the SQL Server is established
Upgraded to version 5.5.1
SEC still connecting to DB using TLS 1.0, even after removing the registry entries.
So to me it looks like SQL 2012 SP4 does not support TLS 1.2 as everything is working fine when I upgraded to SQL 2016 SP1. However, I still need to find out why SEC is still connecting using TLS 1.0. I'm in the process of taking this back to support now.regards,Grant
Hi guys,apologies but I didn't remove the registry entries properly. Once I did, I was back to getting a DB connection error:Back to the support team.regards,Grant
thank you for the detailed post about your procedure. I think ill also upgrade to 2016 to see if it helps.
Let us know how you get on.
So the last thing I have done is the usual SDU logs to the support team, who will probably take them to the product team. On the brightside at least it's now running the latest version of SEC.Ta,Grant
