Our approach to vulnerabilities

That doesn’t mean we’re perfect. If you find a bug, defect, vulnerability, or even just something that seems a bit odd with anything Expel does, please let us know. We believe part of our responsibility is positive engagement with the community and facilitating discourse on making our products (and by extension your enterprise and the internet as a whole) more secure.

We recognize that public security research is a critical and ongoing component of the security industry and we welcome discussion with researchers. Our goal when working with researchers is to be transparent in what we are doing, respectful to all parties involved, and timely in our responses. It’s our vulnerability after all; we’re the ones that need to be responsible.
