The AGC team exceeded expectations and was an exceptional partner to PKWARE. Maria's incredible finesse, deep understanding of the cybersecurity industry, and breadth of M&A experience were crucial in achieving a phenomenal outcome for our shareholders in an extremely challenging global economy. The AGC team worked tirelessly to make it happen and were a pleasure to work with.

Maria has been a trusted advisor to iSIGHT for a number of years. Her deep industry knowledge and relationships across the strategic and investment communities proved invaluable as we grew iSIGHT into a global threat intelligence leader. We're thrilled with this outcome and greatly appreciate Maria's hard work over the years as well as that of her team in helping to guide us to this point. I very much look forward to working with Maria and AGC again in the future.

AGC did a fantastic job advising Xceedium during the M&A process. The management team, Board, and shareholders were all thoroughly impressed by Maria’s deep industry knowledge and close relationships with the major security players. The entire AGC team served as a trusted advisor and helped make this transaction a success. We look forward to working with Maria and her team again in the future.
