Livingston ended a run of four straight Scottish Premiership defeats by holding Hearts to a goalless draw.
The hosts' Steven Naismith had a header disallowed for offside during the opening period and Olly Lee's shot was dealt with by Liam Kelly.
Uche Ikpeazu returned from injury for the hosts as a substitute and had an effort saved.
Livi also had chances with Ryan Hardie and Craig Halkett denied by Colin Doyle but they remain without a goal in 2019.
The two previous meetings at Tynecastle this season had produced just the one goal so it was perhaps naive to expect anything other than a drab, closely-contested match.
The 5-0 drubbing Hearts endured at the hands of the Premiership newcomers in December was Livingston's last victory - eight games ago - and was clearly something of a freak.
But the turgid nature of this encounter will have displeased Gary Holt less than it did Craig Levein, whose Hearts side went into the game on a fine run of five wins from six.
Livingston have now gone eight games without scoring, but the clean sheet at Tynecastle and the point earned as a result are the far more significant statistics as far as they are concerned.
Ultimately it was a deserved point as the visitors frustrated the life out of their opponents, limiting them to minimal opportunities through fabulous organisation, tenacious defending and helped by a dearth of Hearts creativity.
In fairness, it might have been very different had Naismith not had a deft headed goal chopped off early on for offside, after he had glanced Ollie Bozanic's wicked free-kick into the net.
Beyond that, Liam Kelly had little to deal with - an Olly Lee drive from 25 yards was about the strength of it.
Livingston rarely made Doyle work, though the goalkeeper did have to be on his toes to tip a Hardie header over and then to field a thumping Craig Halkett effort from 35 yards.
Hearts claimed for a late penalty as Naismith went down under Chris Erskine's challenge and Ikpeazu headed into Kelly's arms from four yards out but the deadlock was not meant to be broken.
This was Livingston at their dogged best - scrapping and tussling for everything. It was not a thing of beauty, but there is much to be admired about their ethic, which is all about honesty and grit.
They may have slipped down the league in recent weeks, but their place in next season's Premiership is already assured. They will not be dragged into a relegation battle.
This was a frustrating night for Levein, who could have gained ground on Kilmarnock and more ground on Aberdeen.
The return of Ikpeazu is a plus for the Hearts manager. When he came on, he showed what Hearts had been missing in his absence, but even he could not force a winner.
Scottish Cup opponents Auchinleck Talbot are the next visitors to Tynecastle. They will put in a shift too as they look to cause Hearts further frustration.
Hearts manager Craig Levein: "We're kicking ourselves because Aberdeen lost and Kilmarnock drew. We had an opportunity to close up on the teams round about us. That's a bit frustrating.
"The good thing for me is that Uche Ikpeazu came back into the side and looked like he had never been away. He was a real threat when he came on. I thought the team played better when he went on."
Livingston head coach Gary Holt: "Tremendous point. To show our performance and a true grit was really, really pleasing to see.
"They're warriors and that's what we need. We need that game by game. We need to put our bodies on the line. Ryan Hardie's header was just unlucky."
