Systems and methods for providing category—sensitive chat channels

1. A computer-implemented method, comprising:

providing a first category-sensitive chat channel;

assigning a first category level to the first category-sensitive chat channel;

obtaining first content to be posted through the first category-sensitive chat channel;

filtering the first content based at least in part on the first category level; and

providing access to the filtered first content in the first category-sensitive chat channel, wherein the providing of the access to the filtered first content comprises:

receiving a search query for one or more particular chat channels, wherein the one or more particular chat channels comprise a first type of chat channels and a second type of chat channels;

providing first matches to the search query that belong to the first type of chat channels; and

selectively providing second matches to the search query that belong to the second type of chat channels, the selectively providing comprising, for any chat channels belonging to the second type of chat channels:

determining whether a user or a client device from which the search query was received is a member of the chat channel;

providing any of the second matches in which the user or the client device is a member of the chat channel; and

refraining from providing any of the second matches in which the user or the client device is a non-member of the chat channel.

providing access to at least the first portion of the first content in the second category-sensitive chat channel based at least in part on the second category level representing at least one of a higher security classification or sensitivity classification than the first category level.

7. The computer-implemented method of claim 6 , wherein the first portion of the first content is not accessible via the first category-sensitive chat channel.

8. The computer-implemented method of claim 1 , further comprising:

assigning a second category level to the first category-sensitive chat channel to replace the first category level, the second category level representing at least one of a higher security classification or a higher sensitivity classification than the first category level;

determining that a user previously authorized to access the first category-sensitive chat channel at the first category level is no longer permitted to access the first category-sensitive chat channel at the second category level; and

revoking access privileges for accessing the first category-sensitive chat channel from the user.

9. The computer-implemented method of claim 1 , further comprising:

providing a tool for viewing a preview of the first content prior to posting through the first category-sensitive chat channel, the preview of the first content indicating multiple classification levels within the first content.

10. The computer-implemented method of claim 1 , further comprising:

receiving a request to access the first category-sensitive chat channel;

determining that the user does not have authorization to access the first category-sensitive chat channel based at least in part on the first category level being assigned to the first category-sensitive chat channel; and

instructing the user to obtain the authorization.

11. The system of claim 1 , wherein the filtering comprises:

tagging data portions within the first content with security or sensitivity classifications; and

selectively redacting the first content based on the tagged data portions.

12. A system, comprising:

at least one memory storing computer-executable instructions; and

at least one processor configured to access the at least one memory and execute the computer-executable instructions to:

provide a first category-sensitive chat channel;

assign a first category level to the first category-sensitive chat channel;

obtain first content to be posted through the first category-sensitive chat channel;

filter the first content based at least in part on the first category level; and

provide access to the filtered first content in the first category-sensitive chat channel, wherein the providing of the access to the filtered first content comprises:

receiving a search query for one or more particular chat channels, wherein the one or more particular chat channels comprise a first type of chat channels and a second type of chat channels;

providing first matches to the search query that belong to the first type of chat channels; and

selectively providing second matches to the search query that belong to the second type of chat channels, the selectively providing comprising, for any chat channels belonging to the second type of chat channels:

determining whether a user or a client device from which the search query was received is a member of the chat channel;

providing any of the second matches in which the user or the client device is a member of the chat channel; and

refraining from providing any of the second matches in which the user or the client device is a non-member of the chat channel.
