MANILA - The Philippines' largest online stock brokerage, COL Financial, said Friday it discovered a "possible breach" of its clients' personal information.
Clients' account balances and stock positions were unaffected and transactions were not compromised, COL Financial said in a disclosure to the stock exchange.
The company said it took action to strengthen its security systems and reported the matter to the National Privacy Commission.
COL Financial, formerly Citiseconline, is the top broker in the PSE by transaction volume, according to its website.
The possible breach came as the PSE Index hovered at record levels and broke the 8,500 point ceiling for the first time this week.
COL Financial's hotline was unavailable after office hours when contacted by ABS-CBN News.
The brokerage sent e-mails to clients informing them of the potential breach, according to COL Financial's Twitter account.
Established in 1999, COL Financial said it serves over 200,000 customers and has P62 billion in customer assets.
