    Chris  George,  CEO  and  Chief  Architect Protelligent,  Inc.  

  • • Review  actual  cyber  security  incidents   experienced  by  a  CA  public  risk  pool  

    • Understand  what  was  done  to   mitigate/avoid  incidents  in  the  future

    • Hear  expert  advice  regarding  resources   and  solutions  available  to  provide   security  and  risk  mitigation  

    • Learn  what  you  can  do  now

    Overview

  • • Small  businesses  are  making  the  leap  to  computerized   systems  and  digital  records,  and  have  become  attractive   targets  for  hackers.    

    • VISA  estimated  nearly  90%  of  credit  card  data  breaches   reported   in  2013  involved  small  business  customers. 1

    • In  2015,  the  Verizon  Communications  Inc.'s  forensic   analysis  unit,  which  investigates  attacks,  small   organizations  reported  694  security  incidents.  83%  with   confirmed  data  loss  (large  organizations  reported   50,081  incidents,  ~1%  with  confirmed  data  loss)

    Small  Business  Breaches

  • • While  large  businesses  can  dedicate  resources  to   cybersecurity,  small  businesses  face  the  same   cybersecurity  challenges  and  threats  with  limited   resources,  capacity,  and  personnel.  

    • 44%  of  SMBs  reported  being  the  victims  of  a  cyber-­‐ related  attack,  with  an  average  cost  of  approximately   $9,000  per  reported  attack.1

    • Nearly  59%  SMBs  do  not  have  a  contingency  plan  that   outlines  procedures  for  responding  to  and  reporting   data  breaches.2
