On 30 October 2020, the Information Commissioner’s Office (the “ICO”), acting as Lead Supervisory Authority for the purposes of Article 56 of the General Data Protection Regulation (the “GDPR”), issued Marriott International, Inc. (“Marriott”) with a Monetary Penalty Notice
On 30 October 2020, the Information Commissioner’s Office (the “ICO”), acting as Lead Supervisory Authority for the purposes of Article 56 of the General Data Protection Regulation (the “GDPR”), issued Marriott International, Inc. (“Marriott”) with a Monetary Penalty Notice (the “MPN”), fining the hotel chain £18.4 million for breaches of Articles 5(1)(f) and 32 GDPR, in relation to a cyber-attack on Starwood Hotels and Resorts Worldwide, Inc. (“Starwood”) which started in 2014 and remained undetected until September 2018 (by which time Starwood had been acquired by Marriott). This cyber-attack led to personal data (including unencrypted passport details, details of travel, and various other categories of personal information including name, gender, date of birth, VIP status, address, phone number, email address, and credit card data) belonging to approximately 339 million customers being exposed.
Despite the four-year period that the breach spanned, the ICO’s findings are confined only to the period following the implementation of the GDPR: 25 May 2018 to 17 September 2018 (the “Relevant Period”).
The MPN was issued just two weeks after the ICO imposed its largest fine to date - £20 million - on British Airways Limited (“BA”), similarly for breaches of Articles 5(1)(f) and 32 GDPR. An analysis of the BA MPN can be found here.
The two decisions share numerous common features, not least the significant reductions in the final penalty figures as compared to those which were proposed in the ICO’s Notices of Intent (“NOI”). In Marriott’s case, the final figure represents just 18.5% of the £99.2 million fine proposed in the ICO’s NOI dated 5 July 2019 or just over 0.1% of Marriott's worldwide turnover in 2018.
Aside from the useful parallels which can be drawn with the BA MPN, the Marriott MPN is helpful in itself for providing further guidance to organisations on how to ensure that they have “appropriate technical and organisational measures” in place to avoid regulatory sanctions in the event that personal data in their possession is compromised following an IT systems breach.
Data controllers and processors would be well-advised to take heed of the detailed guidance comprised in these MPNs, which build on previous MPNs issued in respect of breaches of the seventh data protection principle under the old data protection regime, at Schedule 1 of the Data Protection Act 19981. Sympathy for those who fail to do so is likely to be in short supply at the ICO which, it is clear, will accept little deviation from the standards set out therein, particularly from well-funded data controllers and processors.
The decision also provides some very helpful guidance regarding how organisations should determine whether to notify relevant Supervisory Authorities for the purposes of Article 33 GDPR, and what steps they are obliged to take to notify affected data subjects in order to fulfil their obligations pursuant to Article 34 GDPR.
The regulatory sanction to which Marriott is subject also serves to highlight the importance of undertaking detailed due diligence, and securing relevant contractual protections, for purchasers undertaking corporate acquisitions.
The facts of the data breach are, by way of summary, as follows:
Marriott notified the ICO initially on 22 November 2018, and later on 30 November 2018, upon discovering additional breaches. Affected data subjects started to be informed of the breach from 30 November 2018, when Marriott issued a press release about the attack and established a dedicated incident website.
The ICO commenced its investigation shortly thereafter, and issued a NOI the following July, informing Marriott of its intention to fine it £99.2 million.
As in BA’s case, Marriott provided three sets of substantive written representations (on 23 August 2019, 31 January 2020, and 17 April 2020).3
Again, the key question invited by this MPN is why the final penalty – as in the BA MPN – is significantly lower than that which was proposed in the ICO’s NOI.
In a similar manner to the BA MPN, the Marriott MPN elides the issue and instead proceeds to analyse the penalty in line with the five-step approach in the ICO’s Regulatory Action Policy (“RAP”).
The key factors at play in the Commissioner’s determination of the quantum of fine included:
An initial figure of £28 million was reached, which was reduced by 20% to £22.4 million, in light of the following mitigating factors13:
As it did in relation to BA, the Commissioner permitted a further reduction of just over £4 million to take into account the impact of Covid-19 on Marriott’s business. The final figure was therefore £18.4 million.
Returning to the question of why this figure is so small by comparison to the fine proposed in the NOI, it is evident that the Commissioner had used – as she had in the BA case – an unpublished internal document entitled “Draft Internal Procedure for Setting and Issuing Monetary Penalties” (“DAP”), which used turnover as the central metric for calculating fines. However, the ICO informed Marriott by way of a letter dated 6 December 2019 – the same date on which BA received an equivalent letter – that the “[DAP] would not be taken into account in setting any penalty imposed on Marriott”.14 The arguments raised by Marriott in their first representations as to the applicability of the DAP appear to have tracked very closely those made by BA in respect of the same subject matter, and were ultimately successful. The Commissioner made clear in the MPN that reliance was solely placed on Article 83 GDPR, section 155 of the Data Protection Act 2018 and the RAP in deciding the quantum of the fine.
The Commissioner otherwise reiterated a number of points in respect of penalty calculations which had been raised in the BA MPN, notably:
The BA MPN was a veritable treasure trove of useful guidance in relation to the Commissioner’s views on “appropriate technical and organisational measures”. The Marriott MPN is no different, albeit with a shift in focus.
Whilst much discussion in the BA MPN was focussed on the steps which might be taken to prevent initial access to IT systems, the Marriott MPN is more focussed on steps which might be taken to identify breaches, and to prevent further unauthorised activity within IT systems, after they have been compromised (issues which were also covered in detail in the BA MPN). This difference in emphasis reflects the fact that, in Marriott's case, the underlying attack had been ongoing since 2014.
Four principal failings were identified by the Commissioner as contributing to her conclusion that “Marriott failed [between 25 May 2018 and 17 September 2018] to process personal data in a manner that ensured appropriate security of the personal data, including protection against unauthorised or unlawful processing and against accidental loss, destruction or damage, using appropriate technical and organisational measures, as required by Article 5(1)(f) and Article 32 GDPR”17, namely:
Perhaps the most notable point to arise from the Commissioner’s analysis of the appropriate technical and organisational measures is the importance of organisations having in place multiple layers of security. The Commissioner acknowledged that “no single security measure can fully protect a system against attack or compromise”. As such, it is wholly appropriate to adopt a strategy of “defence in depth”38. In this regard, the Commissioner was at pains to emphasise, as was the case in the BA MPN, that Marriott had failed to heed publicly available guidance in developing its cyber-security policies and procedures, referring, in particular, to the NCSC's "10 Steps to Cyber Security: Guidance on how organisations can protect themselves in cyberspace, including the 10 steps to cybersecurity"39 and "Introduction to identity and access management"40.
It is also worth noting that, as she did in the BA MPN, the Commissioner rejected the assertion that the sophisticated nature of the attack in any way detracted from culpability: “the sophistication or specific vector of the attack is not the relevant focus”41.
When the Marriott NOI was issued, the Commissioner considered that Marriott had breached both Articles 33 and 34. However, the Marriott MPN finds that, on further consideration, including of Marriott's representations, this was not, in fact, the case. The reasoning behind the Commissioner's findings provides helpful guidance regarding the ICO's interpretations of these aspects of the GDPR.
The Commissioner helpfully clarified the appropriate test to be applied by data controllers when deciding whether to make a notification to the ICO in accordance with Article 33 GDPR.
Marriott had argued that a data controller must be “reasonably certain” that a data breach has occurred before notifying the ICO. The Commissioner disagreed: a data controller “must be able to reasonably conclude that it is likely a personal data breach has occurred to trigger the notification requirement under Article 33”42.
The Commissioner emphasised that, although she considered Marriott had not, in fact, breached Article 34 GDPR, the fact that it had established a dedicated website regarding the breach, and issued a press release in relation to it, was not sufficient to discharge its obligations in this regard43; it was obliged to contact affected data subjects individually (e.g. via email) unless it could be shown that to do so would involve disproportionate effort, which, on the facts, Marriott was unable to demonstrate.
Marriott has stated that it does not intend to appeal the ICO’s decision. In doing so it emphasised, no doubt with a view to the civil claims which it is facing arising out of the breach, that it makes no admission of liability in relation to the Commissioner's findings or the underlying allegations.
Marriott had planned to migrate the data on Starwood's IT systems, which Marriott had improved since it had acquired Starwood, to Marriott's IT systems before GDPR had come into force, and, thereafter, decommission Starwood's IT systems. However, that process was delayed until the end of 2018, meaning that personal data continued to be located on those IT systems after the GDPR came into force.
In the instant case, Marriott's request for clemency on the basis that the IT systems affected were due to be decommissioned, and the fact that it had made improvements to those systems since it acquired Starwood, fell on deaf ears, with the Commissioner emphasising: “the fact that an IT system is due to be retired shortly does not disapply the GDPR to the data being processed through that system”44. Whilst decommissioning “may be a relevant factor in determining what measures would be appropriate in a given case, this ultimately does not remove the basic obligation to put in place security measures appropriate to the risk posed by the continued processing”45.
The message is clear: organisations should not let their guard down just because a system is due shortly to be decommissioned or expect to be relieved of their obligations as data controller pursuant to the GDPR by virtue of the fact that steps have been taken to improve legacy systems following a takeover.
It is hardly surprising that the final penalty imposed on Marriott is significantly lower than that which was proposed in the NOI, not least given: (1) the approach taken by the Commissioner in the BA MPN; and (2) the ICO’s investigations into these breaches, the issuance of NOIs, and thereafter, the process of finalising MPNs (taking into account representations made to the Commissioner), ran in tandem.
However, as we noted in our analysis of the BA MPN, caution should be exercised before interpreting this reduction as an indicator of: (1) the level of futures fines which may be set by the Commissioner; and (2) the approach to calculating fines which will be adopted by the Commissioner in future cases.
Draft statutory guidance published by the ICO in October 2020 on its regulation policy (the “Guidance”) departs from the five-step approach in the RAP, which was relied upon by the Commissioner in both the BA and Marriot MPNs. The Guidance instead sets out a nine step approach, with fines in the first instance being calculated in accordance with turnover. Had the Guidance been applied in relation to Marriott, the starting point for the penalty would have been more than double the proposed figure set out in the NOI46. As we noted previously, assuming the Guidance is finalised in its current form, “mega” fines – running into the hundreds of millions of pounds – remain a distinct possibility.
Whether or not the Guidance is adopted, the Marriott MPN, like the BA MPN, reinforces the importance for organisations seeking to reduce any potential fine as a result of a serious data breach of (most notably):
Given that the fines which have now been levied against BA and Marriott are of a similar order, and reflect a similar approach in terms of the reductions: (1) made by reference to the fines proposed in the NOI; (2) to reflect the impact of Covid-19 on their recipients' operations; and (3) to reflect the recipients' engagement with the ICO's investigations, further guidance as to how turnover will be weighed in the balance would be welcomed by practitioners, data controllers and processors alike.
Our previous analysis on civil claims in respect of BA holds true in relation to Marriott. The upshot of that analysis is, in short, that if all affected guests pursue claims against Marriott, it could be facing liability from those proceedings which may well be many multiples of the fine imposed by the ICO50.
The regulatory sanction to which Marriott is subject also serves to highlight the importance of undertaking careful due diligence, and securing relevant contractual protections, for purchasers undertaking corporate acquisitions.
In the instant case, whilst the Commissioner did accept that “[t]here may be circumstances in which in-depth due diligence of a competitor is not possible during a takeover”51 this was of little relevance, as the Commissioner considered that Marriott had had ample time to address issues which were extant at the time of the Starwood acquisition and following that acquisition, and had failed to address those issues, emphasising: "[t]he need for a controller to conduct due diligence in respect of its data operations is not time-limited or a 'one-off' requirement"52.
Although, regrettably, the Marriott MPN provides little real guidance as to what the ICO would consider best practice in this regard, it is hard to see why a data controller which has acquired a business which has caused data subjects loss by virtue of unlawfully processing, or failing to adequately safeguard, their personal data should be entitled to expect any diminution in the regulatory sanction applicable by virtue of the fact that it conducted thorough due diligence of the target.
Purchasers would instead be well advised to protect themselves in relation to any latent liabilities arising from breaches of data protection legislation on the part of the target company by:

2 Deleted versions of compressed files containing the "dmp" files were located during Marriott's internal investigations into the breaches, indicating that this was likely.
3 As noted in our analysis of the BA MPN, at law Marriott was limited to making a single set of representations. The Commissioner agreed, however, to permit further representations to be made, on the same basis as with BA, namely because of the complexity of the case; Marriott’s representations; and “the fact that this is one of the first major decisions made under the new EU data protection regime”.
4 Paragraph 7.9 of the MPN.
5 Paragraph 7.11 of the MPN.
6 The Commissioner was at pains to note: "Marriott's suggestion that distress will only arise in cases where they are advised by their banks to cancel their payment cards ignores the fact that all personal data (not just financial data) is of significance to individuals, a significance which is reflected in the legal protections afforded to that data under the GDPR."

20 Paragraph 6.13 of the MPN. The failure to secure the “outer ring” of the CDE was not a subject of the MPN. The Commissioner had noted that Marriott had failed to implement complete multi-factor authentication (“MFA”) – which allowed the attacker to exploit a gap in the “outer ring” of the CDE – but that, because Marriott had relied upon two Reports on Compliance, issued by PCI DSS assessors, which stated that MFA was in place for anyone requiring access to the CDE, the Commissioner was satisfied that this did not did not constitute a breach of the GDPR.
