The principal executive office of Issuer is located at 10201 North De Anza Boulevard, Cupertino, California 95014.

Item 2.

Identity and Background.

This statement is being filed pursuant to Rule 13d-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by Blue Coat Systems, Inc. (“Blue Coat”), a Delaware corporation, and Cooper Acquisition, Inc. (“Cooper”), a Delaware corporation. The address of the principal business and the principal office of each of Blue Coat and Cooper is 420 North Mary Avenue, Sunnyvale, California 94085. Blue Coat, a leader in WAN Application Delivery and Secure Web Gateway, secures web communications and accelerates business applications to customers worldwide. Cooper is a wholly-owned subsidiary of Blue Coat.

The name, business address, present principal occupation or employment and citizenship of each director and executive officer (including a director and officer who may be a controlling person) of Blue Coat and Cooper is set forth on Schedule A.

During the last five years, none of Blue Coat, Cooper and, to the knowledge of Blue Coat or Cooper, any of the persons listed on Schedule A, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3.

Source and Amount of Funds or Other Consideration.

On April 20, 2008, Issuer, Blue Coat and Cooper entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Cooper agreed to commence a tender offer (the “Offer”) to acquire all of the outstanding Common Shares at $7.10 per Common Share, in cash, and, subject to the satisfaction or waiver of the conditions to the Offer and the Merger set forth in the Merger Agreement, after consummation of the Offer, Cooper will merge with and into Issuer (the “Merger”), whereupon Cooper’s separate corporate existence will cease and Issuer will continue as the surviving corporation and as a direct, wholly-owned subsidiary of Blue Coat.

As an inducement to enter into the Merger Agreement, and in consideration thereof, Blue Coat, Cooper and Issuer entered into the Tender and Support Agreement (the “Tender and Support Agreement”) dated as of the date of the Merger Agreement with each of the directors and executive officers of Issuer, consisting of the following (each a “Stockholder”):

•

Dave Côté

•

Manuel R. Freitas

Pursuant to the Tender and Support Agreement, each Stockholder has agreed to tender his or her Common Shares in the Offer, and not to withdraw such tender unless the Offer shall have been terminated in accordance with its terms.

In addition, pursuant to the Tender and Support Agreement, each Stockholder granted to the officers of Blue Coat an irrevocable proxy to, at any meeting of the stockholders of Issuer called to vote upon the Merger and the Merger Agreement, and at any adjournment thereof, or in any other circumstances upon which a vote, consent or other approval with respect to the Merger and the Merger Agreement is sought, vote and exercise all voting and related rights of such Stockholder of its beneficially held Common Shares in favor of the adoption by Issuer of the Merger and the approval of the Merger Agreement and each of the transactions contemplated thereby.

Shared voting power with respect to the Common Shares owned by the Stockholders may be deemed to have been acquired through execution of the Tender and Support Agreement. Blue Coat and Cooper have not expended any funds in connection with the execution of the Tender and Support Agreement. Schedule B attached hereto contains the names and number of Common Shares beneficially owned by each Stockholder as of April 20, 2008, as represented by such Stockholder to Blue Coat in the Tender and Support Agreement.

Also, on April 20, 2008, Blue Coat, The Liverpool Limited Partnership (“Liverpool”), and Elliott International, L.P. (“Elliott”) entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) pursuant to which (a) Liverpool agreed to sell 1,423,647 Common Shares to Blue Coat at a price of $7.10 per share and (b) Elliott agreed to sell 2,135,470 Common Shares to Blue Coat at a price of $7.10 per share. The foregoing transaction closed on April 21, 2008, and Blue Coat acquired sole voting power of an aggregate of 3,559,117 Common Shares for an aggregate purchase price of $25,269,730. Blue Coat funded the consideration paid to each of Liverpool and Elliott from its available cash.

We estimate that we will need approximately $253.6 million to purchase all of the outstanding Common Shares not currently owned by Blue Coat or Cooper pursuant to the Offer and to pay all related fees and expenses. Blue Coat and Cooper expect to fund the consideration payable pursuant to the Offer and the Merger from their internally available cash and proceeds from the sale of Blue Coat’s Zero Coupon Senior Convertible Notes due 2013 (the “Notes”) and warrants.

Concurrently with entering into the Merger Agreement, Blue Coat entered into a note purchase agreement (the “Note Purchase Agreement”) with Manchester Securities Corp. and Francisco Partners II, L.P. (together with Manchester Securities Corp., the “Note Purchasers”) pursuant to which, subject to the terms and conditions of such agreement, Blue Coat will be entitled to receive an aggregate of $80 million upon the issuance of the Notes and warrants to the Note Purchasers in a private placement. The Notes and warrants are to be issued following the final expiration of the Offer (without giving effect to any subsequent offer period) and immediately after Cooper’s acceptance for payment of Common Shares pursuant to the Offer.

The foregoing descriptions of the Merger Agreement, the Tender and Support Agreement, the Stock Purchase Agreement and the Note Purchase Agreement do not purport to be complete and are qualified in their entirety by reference to such agreements.

A copy of the Merger Agreement is attached as Exhibit 1 to this Schedule 13D. A copy of the Tender and Support Agreement is attached as Exhibit 2 to this Schedule 13D. A copy of the Note Purchase Agreement is attached as Exhibit 3 to this Schedule 13D. A copy of the Stock Purchase Agreement is attached as Exhibit 4 to this Schedule 13D.

Item 4.

Purpose of Transaction.

As described in Item 3 above, this statement is being filed in connection with the Tender and Support Agreement among Blue Coat, Cooper, Issuer and each of the Stockholders party thereto in connection with the Offer, the Merger and the related Merger Agreement and the Stock Purchase Agreement among Blue Coat, Liverpool and Elliott.

Pursuant to the Merger Agreement, Cooper agreed to commence the Offer as promptly as practicable and in any event by April 30, 2008 (or such later date as the parties may mutually agree in writing). Subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, after consummation of the Offer, Blue Coat shall cause the Merger to occur. Upon the consummation of the Merger, (i) Issuer will become a wholly-owned subsidiary of Blue Coat and (ii) each Common Share which has not been purchased pursuant to the Offer will be converted into the right to receive $7.10 in cash, subject to certain exceptions more fully described in the Merger Agreement.

Page 5 of 11

From and after the effective time of the Merger and pursuant to the Merger Agreement, the directors of Cooper will serve as directors of Issuer until one or more successors are duly elected or appointed and qualified in accordance with applicable law, (ii) the officers of Cooper immediately prior to the effective time of the Merger will be the officers of Issuer until successors are duly elected or appointed and qualified in accordance with applicable law, (iii) the certificate of incorporation of the Issuer will be amended at the effective time of the Merger as set forth in the Merger Agreement and, as so amended, will be the certificate of incorporation of the Issuer as the surviving corporation and (iv) the bylaws of Cooper in effect immediately prior to the effective time of the Merger will be the bylaws of Issuer.

Following the Merger, the Common Shares will no longer be traded on the Nasdaq, there will be no public market for the Common Shares and registration of the Common Shares under the Exchange Act will be terminated.

Except as set forth in this Statement and in connection with the Merger described above, Blue Coat and Cooper have no plan or proposals that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5.

Interest in Securities of the Issuer.

(a) and (b) Other than those Common Shares that may be deemed to be beneficially owned in connection with the Tender and Support Agreements, and the 3,559,117 Common Shares that Blue Coat directly owns and has the sole power to vote and dispose of, neither Blue Coat nor Cooper has acquired or, for the purposes of Rule 13d-4 promulgated under the Exchange Act, beneficially owns any Common Shares.

As a result of the Tender and Support Agreement, Blue Coat and Cooper may be deemed to have the shared voting power of 3,069,559 Common Shares, which Common Shares represent:

•

626,742 Common Shares,

•

2,442,817 Stockholders’ Common Shares subject to stock options exercisable within 60 days of April 1, 2008,

in favor of approval of the Merger Agreement, and thus, for the purpose of Rule 13d-3 promulgated under the Exchange Act, each of Blue Coat and Cooper may be deemed to be the beneficial owner of an aggregate of 3,069,559 Common Shares. All Common Shares that may be deemed to be beneficially owned by Blue Coat constitute approximately 17.0% of the issued and outstanding Common Shares as of March 31, 2008 (based upon the number of issued and outstanding Common Shares represented by Issuer in the Merger Agreement), plus the Stockholders’ Common Shares subject to stock options exercisable within 60 days of April 1, 2008. All Common Shares that may be deemed to be beneficially owned by Cooper constitute approximately 7.9% of the issued and outstanding Common Shares as of March 31, 2008 (based upon the number of issued and outstanding Common Shares represented by Issuer in the Merger Agreement), plus the Stockholders’ Common Shares subject to stock options exercisable within 60 days of April 1, 2008.

Blue Coat and Cooper (i) are not entitled to any rights as stockholders of Issuer as to the Common Shares covered by the Tender and Support Agreement, except as otherwise expressly provided in the Tender and Support Agreement and (ii) disclaim all beneficial ownership of such Common Shares.

Except as set forth in this Item 5(a) and (b), none of Blue Coat, Cooper and, to the knowledge of Blue Coat or Cooper, any person named in Schedule A beneficially owns any Common Shares.

(c) Except for the agreements described above, to the knowledge of Blue Coat or Cooper, no transactions in the class of securities reported have been effected during the past 60 days by any person named in Schedule A or Item 5(a) and (b).

Page 6 of 11

(d) To the knowledge of Blue Coat or Cooper, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities of Issuer reported herein.

(e) Inapplicable.

Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Except for the agreements described above, to the knowledge of Blue Coat or Cooper, there are no contracts, arrangements, understandings or relationships (legal or otherwise), including, but not limited to, transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, between the persons enumerated in Item 2 and any other person, with respect to any securities of Issuer, including any securities pledged or otherwise subject to a contingency the occurrence of which would give another person voting power or investment power over such securities other than standard default and similar provisions contained in loan agreements.
