I think it is unlikely that anyone is going to review what to them must be a random blog without some kind of reward or compensation. Providing qualified and meaningful feedback on someone's writing is a lot of work, and I don't see why anyone would do that hard and time consuming job for free.
Therefore, in my opinion, you have two options:
You can pay an editor with a background in your field to provide feedback.
If your blog is successful and becomes a well-known ressource in your field, other professionals will note it and review it.

Based on your comment, I must assume the question you want to ask is:
"Where can I find an editor with a background in technology and cybersecurity?"
The answer to that question would be:
There are several ways to find an editor. I'll sort them by most recommended:
Contact writers in your field and ask them who edited their work, what their experiences where, and who they would recommend.
Peruse business directories such as:
a. https://www.the-efa.org/hiring/
b. https://aceseditors.org/resources/for-hire
c. https://naiwe.com/
d. https://www.pensite.org/
e. http://www.editorsforum.org/
f. https://www.edsguild.org/for-clients/
g. https://www.bookeditorsalliance.com/
h. https://www.independenteditorsgroup.com/
and others.
Use terms like "editor cybersecurity" in your search engine of choice.
