                               POWER OF ATTORNEY

      The undersigned, as a Section 16 reporting person of Qualys, Inc. (the
"Company"), hereby constitutes and appoints Bruce Posey, as the undersigned's
true and lawful attorney-in-fact to:

      1.    complete and execute Forms 3, 4 and 5 and other forms and all
            amendments thereto as such attorney-in-fact shall in his discretion
            determine to be required or advisable pursuant to Section 16 of the
            Securities Exchange Act of 1934 (as amended) and the rules and
            regulations promulgated thereunder, or any successor laws and
            regulations, as a consequence of the undersigned's ownership,
            acquisition or disposition of securities of the Company; and

      2.    do all acts necessary in order to file such forms with the SEC, any
            securities exchange or national association, the Company and such
            other person or agency as the attorney-in-fact shall deem
            appropriate.

      The undersigned hereby ratifies and confirms all that said attorney-in-
fact and agents shall do or cause to be done by virtue hereof.  The undersigned
acknowledges that the foregoing attorney-in-fact, in serving in such capacity at
the request of the undersigned, is not assuming, nor is the Company assuming,
any of the undersigned's responsibilities to comply with Section 16 of the

unless earlier revoked by the undersigned in a signed writing delivered to the
Company and the foregoing attorney-in-fact.

      IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
