Systems and methods for controlling email access

1. A system, comprising:

an apparatus comprising at least one processor and at least one memory storing program code instructions, the at least one memory and program code instructions being configured to, with the at least one processor, cause the apparatus to at least:

identify at least one resource rule associated with a particular client device, wherein at least one email resource is accessible to the particular client device, wherein the at least one email resource comprises at least one uniform resource locator (URL), and wherein the particular client device may only be authorized to access the at least one email resource in an instance in which at least a threshold of the at least one resource rule is satisfied;

determine whether at least one of the identified at least one resource rule comprises a resource rule specifying that the particular client device is only authorized to access the at least one email resource in an instance in which the at least one URL is configured to be exclusively accessible via a particular browser application, the at least one URL being configured to be exclusively accessible via the particular browser application in an instance in which the at least one URL is configured such that the at least one URL cannot be accessed via at least one browser application other than the particular browser application; and,

in an instance in which it is determined that at least one of the identified at least one resource rule comprises the resource rule specifying that the particular client device may only be authorized to access the at least one email resource in an instance in which the at least one URL is configured to be exclusively accessible via the particular browser application:

determine whether the at least one URL is configured to be exclusively accessible via the particular browser application; and,

in an instance in which it is determined that the at least one URL is not configured to be exclusively accessible via the particular browser application, modify the at least one URL such that the modified at least one URL is configured to be exclusively accessible via the particular browser application.

2. The system of claim 1 , wherein the modified at least one URL comprises at least one encrypted URL.

3. The system of claim 1 , wherein the apparatus is further caused to at least:

transmit the at least one email resource to the particular client device.

4. The system of claim 1 , wherein the apparatus is further caused to at least:

authorize the particular client device to access the at least one email resource.

5. A method, comprising:

identifying, via at least one processor, at least one resource rule associated with a particular client device, wherein at least one email resource is accessible to the particular client device, wherein the at least one email resource comprises at least one uniform resource locator (URL), and wherein the particular client device may only be authorized to access the at least one email resource in an instance in which at least a threshold of the at least one resource rule is satisfied;

determining whether at least one of the identified at least one resource rule comprises a resource rule specifying that the particular client device is only authorized to access the at least one email resource in an instance in which the at least one URL is configured to be exclusively accessible via a particular browser application, the at least one URL being configured to be exclusively accessible via the particular browser application in an instance in which the at least one URL is configured such that the at least one URL cannot be accessed via at least one browser application other than the particular browser application; and,

in an instance in which it is determined that at least one of the identified at least one resource rule comprises the resource rule specifying that the particular client device may only be authorized to access the at least one email resource in an instance in which the at least one URL is configured to be exclusively accessible via the particular browser application:

determining whether the at least one URL is configured to be exclusively accessible via the particular browser application; and,

in an instance in which it is determined that the at least one URL is not configured to be exclusively accessible via the particular browser application, modifying the at least one URL such that the modified at least one URL is configured to be exclusively accessible via the particular browser application.

6. The method of claim 5 , wherein the modified at least one URL comprises at least one encrypted URL.

7. The method of claim 5 , further comprising:

authorizing the particular client device to access the at least one email resource.

8. A computer program product comprising a non-transitory computer-readable storage medium having program code portions embodied therein, the program code portions being configured to, upon execution by a processor, cause apparatus to at least:

identify at least one resource rule associated with a particular client device, wherein at least one email resource is accessible to the particular client device, wherein the at least one email resource comprises at least one uniform resource locator (URL), and wherein the particular client device may only be authorized to access the at least one email resource in an instance in which at least a threshold of the at least one resource rule is satisfied;

determine whether at least one of the identified at least one resource rule comprises a resource rule specifying that the particular client device is only authorized to access the at least one email resource in an instance in which the at least one URL is configured to be exclusively accessible via a particular browser application, the at least one URL being configured to be exclusively accessible via the particular browser application in an instance in which the at least one URL is configured such that the at least one URL cannot be accessed via at least one browser application other than the particular browser application; and,

in an instance in which it is determined that at least one of the identified at least one resource rule comprises the resource rule specifying that the particular client device may only be authorized to access the at least one email resource in an instance in which the at least one URL is configured to be exclusively accessible via the particular browser application:

determine whether the at least one URL is configured to be exclusively accessible via the particular browser application; and,

in an instance in which it is determined that the at least one URL is not configured to be exclusively accessible via the particular browser application, modify the at least one URL such that the modified at least one URL is configured to be exclusively accessible via the particular browser application.

9. The computer program product of claim 8 , wherein the modified at least one URL comprises at least one encrypted URL.

10. The computer program product of claim 8 , wherein the apparatus is further caused to at least:

transmit the at least one email resource to the particular client device.

11. The computer program product of claim 8 , wherein the apparatus is further caused to at least:

authorize the particular client device to access the at least one email resource.
