KeeProve Master PLUS

The risks of handling electronic public notices in-house can be broadly categorized into four types.

1. Invalidation of public notice due to interruption constituting at least one-tenth of the public notice period Because electronic public notices are disclosed online, stricter legal requirements for posting apply than in the case of traditional newspaper notices.The invalidation of a public notice significantly impacts corporate actions.
2. Servers subject to downtime due to breakdown, maintenance, disasters or other such circumstances If a server experiences downtime due to hardware failure, scheduled maintenance, disasters, or other unforeseen circumstances, users will be unable to access the data. This will not be promptly recognized without the management of website operations, potentially leading to situations where notices are not being posted.
3. Inaccessibility of data due to situations such as cyberattacks on servers Listed companies face more frequent server attacks due to the increased attention on them, potentially causing server overload and rendering data inaccessible in some cases.
4. Public notice data becoming subject to tampering during posting period Various forms of unauthorized access may result in tampering of the public notice data itself. Should unforeseen circumstances occur, this could not only significantly impact the company itself but also cause damage to shareholders and investors.

KeeProve Master PLUS resolves these risks.
KeeProve Master PLUS is a service that enables clients to safely, reliably, and continuously post important disclosure information on their websites.

Electronic public notices require not only simply posting public notice data on websites but also ensuring that the notices remain continuously disclosed for the period stipulated by law.
Furthermore, investigations by investigative bodies are mandatory.
If the posting is deemed to have been interrupted, an additional notice outlining the interruption is required. Moreover, strict rules dictate that if the cumulative posting period falls below nine-tenths of the public notice period, the public notice itself becomes invalid.
We provide a secure storage and posting service that alleviates risks and burdens associated with electronic public notices.
